Yard Square (abbreviations: yd2, or sy): is an imperial unit of area, formerly used in most of the English-speaking world but now generally replaced by the square metre, however it is still in widespread use in the U.S., Canada and the U.K. It is the area of a square with sides of one yard (three feet, thirty-six inches, 0.9144 metres) in length.

Millimeter Square (abbreviation: mm2): is the SI derived unit of area. It is the area of a square whose sides measure exactly one millimeter. The square millimeter is derived from the SI base unit of the metre, which itself is the length of the path travelled by light in absolute vacuum within time interval of 1/299,792,458 * 1/1000 of a second.

How to Convert Yards Square to Millimeters Square

Example: How many millimeters square are equivalent to 2 yards square?


1 yards square = 836127 millimeters square

2 yards square = Y millimeters square

Assuming Y is the answer, and by criss-cross principle;

Y equals 2 times 836127 over 1

(i.e.) Y = 2 * 836127 / 1 = 1672254 millimeters square

Answer is: 1672254 millimeters square are equivalent to 2 yards square.
