## What is square millimeters calculator?

The square millimeters calculator is measured an area in millimeters so it’s called the square millimeters area. This sq mm calculator is used to determine the area of rectangles. If a shape has an area of one square millimeter, it can be said to be 1 sq mm area.

## Square millimeters Formula

The formula for calculating the square millimeters is

**SMM = L * W**

- SMM = Square Millimeters
- L = Length of a rectangle in millimeters
- W = Width of a rectangle in millimeters

Square millimeters = length(millimeter) x width(millimeter)

If you calculate the total cost area then used this formula:-

Total cost Area = Area in Square millimeter * Price per square millimeters
