Convert Square millimetres to Square yards
1 square millimetre is 0.000001196 sq yd. One square millimetre is exactly 0.0000011959900463 square yards.
One square millimetre is 1.1960 × 10^-6 square yards. To convert square millimetres to square yards, multiply by 1.1960 × 10^-6; to go the other way, divide by 1.1960 × 10^-6 or multiply by 836127.36. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Office of Weights and Measures. A millionth of a square metre, because the millimetre is a thousandth of a metre and area squares the factor.

Factors are entered by hand from NIST Office of Weights and Measures rather than derived from a units library, so the ones that terminate are exact rather than rounded.
The same converter answers this pair however it is written: sqmm to sqyd is how the symbols are typed on a keyboard with no superscript on it.
How do you convert square millimetres to square yards? The converter and the working
- 1.Take the measurement in square millimetres.
- 2.Multiply by 1.1960 × 10^-6 — that is how many square yards fit in one square millimetre.
- 3.To go back the other way, divide by 1.1960 × 10^-6, or multiply by 836127.36.
Worked example: 25 square millimetres to square yards
- Formula
- mm² × 1.1960 × 10^-6 = sq yd
- Arithmetic
- 25 × 1.1960 × 10^-6 = 0.0000299 sq yd
- Answer
- 25 mm² = 0.0000299 sq yd
The factor is rounded for display; the figure above is computed from the full value.

What is a square millimetre?
A millionth of a square metre, because the millimetre is a thousandth of a metre and area squares the factor. The working unit of engineering drawings and of cable cross-sections.
What is a square yard?
Nine square feet. Carpet is still sold this way in much of the trade.
How many square yards are in a square millimetre?
One square millimetre is 1.1960 × 10^-6 square yards. Going the other way, one square yard is 836127.36 square millimetres. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
