Centimeter Square (abbreviation: cm2): is the SI derived unit of area. It is the area of a square whose sides measure exactly one centimeter. The square centimeter 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 * 1/100 of a second.

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 Centimeters Square to Kilometers Square

### Example: How many kilometers square are equivalent to 63.01 centimeters square?

As;

1 centimeters square = 1.0E-10 kilometers square

63.01 centimeters square = Y kilometers square

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

Y equals 63.01 times 1.0E-10 over 1

(i.e.) Y = 63.01 * 1.0E-10 / 1 = 6.301E-9 kilometers square

Answer is: 6.301E-9 kilometers square are equivalent to 63.01 centimeters square.
