**Definitions:**

**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.

**Kilometer Square** (abbreviation: **km2**): is the SI derived unit of area. It is the area of a square whose sides measure exactly one kilometre. The square metre 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 * 1000 of a second.

## How to Convert Yards Square to Kilometers Square

*Example: How many kilometers square are equivalent to 63.97 yards square?*

As;

1 yards square = 8.3612736E-7 kilometers square

63.97 yards square = Y kilometers square

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

Y equals 63.97 times 8.3612736E-7 over 1

(i.e.) Y = 63.97 * 8.3612736E-7 / 1 = 5.34870672192E-5 kilometers square

Answer is: 5.34870672192E-5 kilometers square are equivalent to 63.97 yards square.
