Where these units come from
Square units need no definition of their own: a square metre is a metre by a metre, and everything follows from the length. The land measures are older and stranger. The acre began as the land a yoke of oxen could plough in a day, which is why it was long and thin rather than square — one chain by one furlong, 4840 square yards. The hectare and the are came out of the French Revolution, when land had to be measured in something decimal; neither belongs to the International System, but both were kept for land because a hectare is a comfortable size to picture and a square metre is not. Since the 1959 agreement on the yard, the acre is exactly 4046.8564224 square metres, so the conversions on this page are exact rather than approximate.
Where you meet them
Square metres price flats, size carpets and decide how much paint a wall needs; square feet do the same work in the United States and in much of the property market worldwide. Hectares belong to farmland, forests and planning permissions; acres to land deeds in the English-speaking world. Square kilometres and square miles are for countries, lakes and fires. Square centimetres and square millimetres live in workshops, on datasheets and anywhere a cross-section matters.
Questions people ask
How do I think about square feet?
A square foot is 0.09290304 square metres exactly, so a square metre is about 10.76 square feet. In the United States and in British property listings, floor space is given in square feet: a 100 square metre flat is a little under 1,100 square feet. Divide by ten and a bit to go from feet to metres.
Where is the square yard used?
Mostly for carpet, turf and paving in the UK and the US. A square yard is nine square feet and exactly 0.83612736 square metres, so it is a little under a square metre. Remember that it is not three feet of floor but three feet by three feet.
Is the answer exact?
Where both units are defined in terms of one another by whole numbers, yes — the page says so above the figure, and the only rounding is in how many digits are shown. Where the ratio has no finite decimal, the page shows twelve significant digits and says the relation is approximate rather than pretending otherwise.

Nine square feet to the square yard: a conversion that needs no calculator
A yard is three feet, so a square yard is three feet by three feet, a block of nine square feet. That makes this one of the easiest area conversions in daily life: to convert ft² to yd² you divide by nine. So 18 ft² is 2 yd², 90 ft² is 10 yd², and 450 ft² is 50 yd², the size of a pallet of lawn turf. The only real danger is dividing by three instead of nine, which makes every answer three times too big. This page does the division as you type, and the text below shows where the conversion appears, from carpet shops to plots of land in India and Pakistan.

How to convert ft² to yd²: divide by 9
The rule
One square yard equals exactly 9 square feet. To convert ft² to yd², divide the square feet by 9. So 27 ft² is 3 yd², 100 ft² is 11.11 yd², 450 ft² is 50 yd² and 1,000 ft² is 111.1 yd². In the other direction, multiply the square yards by 9.
Worked examples
A room of 12 by 15 feet has 180 ft², which is 20 yd². A rug of 9 by 12 feet has 108 ft², 12 yd². A garden of 2,000 ft² is 222.2 yd². When the division is not exact, keep two decimals, or say it in whole yards and a fraction: 100 ft² is 11 1/9 square yards.
A grid of three by three
Draw a square, divide it into three rows and three columns, and you have a square yard with nine small squares, each a square foot. The picture is the best way to remember why the factor is nine, and why using three would be wrong.
A quick check
The square yard is the larger unit, so the number must shrink to a ninth. If your “convert ft² to yd²” calculation gave you a number only a third of the original, you divided by three.
The square foot
One foot by one foot
The square foot is 144 square inches, or 0.092903 square metres. It measures floor area in North American homes, offices and shops. Rents and prices are quoted per square foot.
Everyday sizes
A small bathroom is 40 ft², a bedroom 120 to 180, a garage 400, an average new house 2,400.
The square yard
Three feet by three feet
The square yard is 9 square feet, or 0.836127 square metres. It is used for carpet, turf, pavement and land plots in the United States, the United Kingdom, India, Pakistan and other countries influenced by the British system. A square yard is about the size of a small bath mat.
Where it lives
Carpet and flooring shops, landscape suppliers, road contractors and property agents in South Asia all use square yards.
Square foot and square yard compared
A square yard holds nine square feet. For a room, the foot is more precise; for a roll of carpet or a lawn, the yard gives shorter numbers. The conversion is exact and simple, which is why people can do it in their heads.
A caution applies to the linear conversion. A yard is three feet long, but a square yard is nine square feet. Many people forget this and divide by three when they work with areas, which is the root of most errors.
Where the conversion appears
Carpets and rugs
Carpet in the United Kingdom and the United States is sold by the square yard. A room of 12 by 15 feet needs 20 yd², and with 10 per cent waste, 22 yd². A rug of 9 by 12 feet is 12 yd². A shop that quotes 25 dollars per square yard charges 2.78 dollars per square foot. A “convert ft² to yd²” calculation makes the price comparison fair.
Turf and sod
A pallet of sod covers about 450 ft², 50 yd². A lawn of 3,000 ft², 333 yd², needs about 6.7 pallets. Landscapers sell by the pallet or by the square yard and plan in square feet, so the conversion is part of every quote.
Paving and roads
Road and parking contractors price asphalt per square yard. A driveway of 20 by 60 feet, 1,200 ft², is 133 yd². At 15 dollars per square yard laid, it costs 2,000 dollars. The same job quoted per square foot, 1.67, would sound cheaper, so check the unit.
Football and sports fields
An American football field including the end zones is 360 by 160 feet, 57,600 ft², which is exactly 6,400 yd². A tennis court is 2,808 ft², 312 yd². A baseball diamond has an infield of about 8,100 ft², 900 yd². Groundsmen think in square yards when they order seed and turf, because the number is shorter.
Vinyl, linoleum and sheet flooring
Sheet vinyl comes in rolls 12 feet wide. A kitchen of 10 by 12 feet needs 120 ft², 13.3 yd², but since the width is fixed you buy 4 yards of length, 48 ft², no, 10 feet of length at 12 feet width, 13.3 yd². The conversion helps you work out how much to buy and compare it with the price per square yard.
Car parks and driveways
A parking space of 9 by 18 feet is 162 ft², 18 yd². A car park for 50 cars with aisles is about 15,000 ft², 1,667 yd². Surface treatments such as sealcoating are priced per square yard, so the conversion appears in every maintenance contract.
Rounding
The factor 9 is exact, so nothing needs to be rounded until the end. For fractions, 1/9 is 0.1111, and you can keep four decimals if you convert a small area. For prices, round the result up to the next whole square yard to avoid running short.
Spreadsheet use
Write square feet in column A and =A2/9 in column B. For the reverse use =B2*9. Format with two decimals. A third column dividing by 10.7639 gives square metres, so you read the area in three units.
Teaching the idea
Use three metre sticks or three rulers to make a square on the floor, one yard by one yard. Then mark the nine one foot squares inside it with tape. Children see at once why the factor is nine, and can predict the answer before they calculate.
Old units of area
Before standardisation, local square yards varied slightly between countries and trades. The modern yard was fixed at 0.9144 metres in 1959, so the square yard is exactly 0.83612736 square metres. Old contracts may therefore refer to slightly different values, a small difference that matters only for large plots.
Swimming pools and ponds
A pond of 12 by 20 feet, 240 ft², is 26.7 yd². A pool of 16 by 32 feet, 512 ft², is 56.9 yd². Liners are sold by the square yard in some markets, and a “convert ft² to yd²” calculation lets you calculate the cost before you order.
Wall coverings and murals
A wall of 8 by 12 feet, 96 ft², is 10.7 yd². A mural of 10 by 20 feet, 200 ft², is 22.2 yd². Painters estimate in square feet, but wall covering suppliers may quote by the yard or the roll.
Why 3 times 3 is the key
Every area conversion is the square of the length conversion. A yard is 3 feet, so a square yard is 3 squared, 9 square feet. A metre is about 3.28 feet, so a square metre is 10.76 square feet. Once you see this pattern, you can derive any factor you need without a table.
Playgrounds and safety surfacing
Playground safety surfacing, such as rubber mulch or poured rubber, is priced by the square yard in some markets. A play area of 30 by 40 feet is 1,200 ft², 133 yd². Standards specify a fall zone extending 6 feet around equipment, so a swing set of 12 by 16 feet needs a surfaced area of 24 by 28 feet, 672 ft², 75 yd². A “convert ft² to yd²” calculation makes quotes from different suppliers comparable.
Roofing squares
A roofer's square is 100 square feet, which equals 11.1 square yards. A roof of 25 squares is 2,500 ft², 278 yd². Shingles are sold by the square, and underlay by the roll. The three units, feet, yards and squares, appear on the same invoice.
Weed barrier and landscape fabric
Landscape fabric is sold in rolls such as 3 by 100 feet, 300 ft², which is 33.3 yd². A flower bed of 12 by 20 feet, 240 ft², 26.7 yd², takes most of one roll. Gardeners buy by the roll, calculate in feet and sometimes read coverage in square yards on the label, so the nine to one ratio is useful on the garden centre floor.
Sports turf and golf greens
A golf putting green of 5,000 ft² has 556 yd². A bowling green of 120 by 120 feet, 14,400 ft², is 1,600 yd². Greenkeepers order seed, sand and fertiliser by the yard or by the thousand square feet, and the dosage on the label may use either, so a “convert ft² to yd²” calculation is the first step in every spreading plan.
Tents, marquees and event floors
A marquee of 20 by 40 feet is 800 ft², 89 yd², and holds about 80 seated guests at 10 ft² each. Temporary flooring comes in panels of 3 by 3 feet, exactly one square yard each, so a marquee of that size needs 89 panels. The match between panel size and unit makes planning trivial.
Insulation, underlay and membranes
Carpet underlay is sold by the roll, usually 15 yd² or 135 ft², and waterproofing membranes by the square yard. A room of 180 ft², 20 yd², takes one and a half rolls of underlay, so you buy two. Order forms mix feet and yards, and a quick division by nine avoids buying twice what you need.
Checking an answer by picture
Imagine a doormat of one yard by one yard. Nine square tiles of one foot would cover it completely. If you convert a room of 90 ft² and get 30, you can see that something is wrong, because ten doormats are needed for 90 ft², not thirty. A mental picture like this catches the error of dividing by three, and a “convert ft² to yd²” calculation that passes the picture test is almost always right. Make the check before you order any material, and your order will be correct.
Plots in India
In Indian real estate, small plots are priced and sold by the square yard, locally called gaz or gajam. A plot of 200 square yards is 1,800 ft², 167 m². Prices in cities like Hyderabad are quoted per square yard. A buyer from abroad should always convert the area to square feet or metres before comparing.
Marla and kanal in Pakistan
In Pakistan and parts of India, a marla is 272.25 ft², which is 30.25 yd² or 25.3 m². A kanal is 20 marla, 5,445 ft², 605 yd², 506 m². Houses are sold in units of 5, 10 or 20 marla, and a “convert ft² to yd²” calculation puts them in a form that a foreign buyer can compare with plots elsewhere.
Cent and guntha in South India
South Indian land is measured in cents, each 435.6 ft², 48.4 yd², and in guntas, each 1,089 ft², 121 yd². A plot of 5 cents is 2,178 ft², 242 yd², 202 m². An acre is 100 cents, 43,560 ft², 4,840 yd². These local units fit neatly into the square yard.
Gardens in Britain
A British terraced house may have a garden of 400 ft², 44 yd². A semi detached house has 1,200 ft², 133 yd². A large suburban garden is 3,000 ft², 333 yd², or 279 m². Real estate agents quote gardens in feet or metres, and gardeners buy turf, seed and fertiliser by the square yard.
Concrete slabs and patios
A patio slab of 12 by 15 feet is 180 ft², 20 yd². At a thickness of 4 inches it needs 2.2 cubic yards of concrete. Contractors speak of area in square feet and volume in cubic yards. The conversion from area to cubic yards involves the thickness as well as the area, so a “convert ft² to yd²” calculation is only the first step.
Fabric and upholstery
A piece of upholstery fabric of 54 inches width and 3 yards length covers 4.5 by 9 feet, 40.5 ft², 4.5 yd². Fabric shops sell by the yard of length, and the area depends on the width. A sofa that needs 12 yards of 54 inch fabric uses 12 yards by 1.5 yards, which is 18 yd².
Mulch, gravel and ground cover
Garden suppliers sell mulch by the cubic yard. A bed of 300 ft², 33 yd², covered 3 inches deep needs 2.8 cubic yards. The area in square yards is a step toward the volume, and customers often quote the bed in feet but pay for yards.

Mistakes when you convert ft² to yd²
Dividing by 3
That is the length factor. For area, divide by 9.
Multiplying instead of dividing
The square yard is the bigger unit, so the number shrinks. If 90 ft² became 810, you multiplied.
Confusing with cubic yards
A cubic yard is 27 cubic feet. Do not mix area and volume units.
