**Definitions:**

**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.

**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 Millimeters Square to Centimeters Square

*Example: How many centimeters square are equivalent to 85.09 millimeters square?*

As;

1 millimeters square = 0.01 centimeters square

85.09 millimeters square = Y centimeters square

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

Y equals 85.09 times 0.01 over 1

(i.e.) Y = 85.09 * 0.01 / 1 = 0.8509 centimeters square

Answer is: 0.8509 centimeters square are equivalent to 85.09 millimeters square.
