**Definitions:**

**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.

**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 Centimeters Square to Millimeters Square

*Example: How many millimeters square are equivalent to 50.53 centimeters square?*

As;

1 centimeters square = 100 millimeters square

50.53 centimeters square = Y millimeters square

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

Y equals 50.53 times 100 over 1

(i.e.) Y = 50.53 * 100 / 1 = 5053 millimeters square

Answer is: 5053 millimeters square are equivalent to 50.53 centimeters square.
