**Definitions:**

**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.

**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.

## How to Convert Kilometers Square to Centimeters Square

*Example: How many centimeters square are equivalent to 15 kilometers square?*

As;

1 kilometers square = 10000000000 centimeters square

15 kilometers square = Y centimeters square

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

Y equals 15 times 10000000000 over 1

(i.e.) Y = 15 * 10000000000 / 1 = 150000000000 centimeters square

Answer is: 150000000000 centimeters square are equivalent to 15 kilometers square.
