CM to Yards Converter

Common questions

How many centimetres are in a yard?

Exactly 91.44. The 1959 agreement fixed the international yard at 0.9144 metres, so the centimetre figure is a definition and nothing in it is rounded: 91.44 cm, 914.4 mm, 36 inches and 3 feet are all the same length. Type 91.44 into the From box and the headline reads 1, with nothing trailing after the decimal point. The neighbours are just as clean: 45.72 cm is 0.5 yd, 182.88 cm is 2 yd, 274.32 cm is 3 yd and 914.4 cm is 10 yd.

How do you convert cm to yards?

Divide the centimetres by 91.44. That is the whole conversion: 100 cm is 1.09361329834 yd, 150 cm is 1.64041994751 yd and 1,000 cm is 10.9361329834 yd. Multiplying by 0.0109361329834, which is what one centimetre is worth in yards, gives the same digits shown here, but the division is the one to do by hand, because 91.44 is the exact number and the decimal is not.

How many yards is a metre?

1.09361329834 yards, because a metre is 100 cm and a yard is 91.44 cm. The metre is the longer of the two by 8.56 cm, a little over 9%, which is the whole reason the two units are worth converting rather than treating as the same. Longer runs scale the same way: 10 m is 10.9361329834 yd and 100 m is 109.361329834 yd, so a 100 m sprint is about nine yards longer than the 100 yards between the goal lines on an American football field.

How many yards of fabric is a metre, and how much should I buy?

Cloth sold by the metre comes off the roll in 100 cm lengths and cloth sold by the yard in 91.44 cm lengths, so three metres is 3.28083989501 yd and three yards is 274.32 cm, or 2.7432 m. If a pattern asks for yards and the shop sells metres, buying the same count in metres leaves you a little over 9% long, which is usually harmless. Going the other way costs you: four yards where the pattern wants four metres is 365.76 cm against 400 cm, so you finish 34.24 cm short. Width is measured separately and is not affected by the conversion.

How do I read a decimal yard as feet and inches?

Multiply the part after the point by 3 to get feet, then multiply what is left by 12 to get inches. The converter prints 100 cm as 1.09361329834 yd, so 0.09361329834 times 3 is 0.28 of a foot, which is no whole feet, and 0.28 times 12 is 3.4 in: 1 yd 0 ft 3.4 in. The Inch row under the answer agrees, at 39.3700787402 in, which is 36 plus 3.37. The headline stays in decimal yards because that is the number a spreadsheet or an order form wants, and the chart at the foot of this page prints both forms together.

Is a US yard the same as an imperial yard?

Yes, and that is unusual for a US against imperial pair. Since the international agreement of 1959 both are exactly 0.9144 metres, so 91.44 cm serves for both and there is no ambiguity in this conversion at all. Volume is where the two systems really part company: a US gallon is 3.785 litres and an imperial gallon is 4.546. The one length exception is the US survey yard of 3600/3937 m, used in land surveying and retired at the end of 2022. It is longer by two parts in a million, about 3 mm over a whole mile. Every figure on this page uses the international yard.

What else does the page show under the answer?

The same measurement in every common length unit, each with its own Copy button: millimetres, metres, kilometres, inches, feet, yards, miles and nautical miles. One metre typed as 100 cm is 1,000 mm, 1 m, 39.3700787402 in, 3.28083989501 ft and 0.000621371192237 mi at once. The Uncommon units switch in the bar above the list adds seven more, from nanometres and thous to furlongs, astronomical units, light years and parsecs, and the two unit menus stay open the whole time, so the same number will go from centimetres to any of them without leaving this page.

How do I convert yards back to centimetres?

Press Swap units, the button between the two boxes, and the pair reverses without reloading the page: 1 yd gives 91.44 cm, 2.5 yd gives 228.6 cm, and 100 yd, the distance between the goal lines on an American football field, gives 9,144 cm, which is 91.44 m. Going that way the division becomes a multiplication by 91.44, and it is exact in both directions, since the factor itself is a definition.

Why does this page open on centimetres and yards when I last converted something else?

Because a page that names a pair should show that pair. This one sets Centimetre and Yard on arrival, ahead of whatever the converter last remembered, and it leaves the main unit converter's own memory alone: go back there and it is still on the pair you left it on. The number you last typed does travel with you, since it is usually the one you are still working on.

How precise is the answer, and can I copy it?

The conversion is a single division carried out in double precision, and the result is printed to twelve significant digits with trailing zeros dropped, so 91.44 cm reads 1 and 45.72 cm reads 0.5, while 1 cm reads 0.0109361329834. Twelve digits sits well inside what a double carries and absorbs the floating-point residue a chained conversion leaves behind. Copy result puts the headline on your clipboard exactly as printed but without the thousands separators, and every row in the list below has its own Copy button. Anything that is not a number, a stray letter or a second decimal point, gets a message quoting back what you typed instead of a silent zero. Nothing you type is sent anywhere: the conversion is arithmetic against a table of factors that ships with the page, so it keeps working with no network connection once the page has loaded.
