What is a square yard?
Nine square feet. Carpet is still sold this way in much of the trade.
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.
How many square millimetres are in a square yard?
One square yard is 836127.36 square millimetres, exactly. Going the other way, one square millimetre is 1.1960 × 10^-6 square yards. 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.
