About this

A single linear centimeter contains 10 millimeters. Because area is mathematically calculated using two dimensions, scaling an area down means multiplying the linear dimension by itself: 10 × 10 = 100. This perfectly demonstrates why one square centimeter is composed of exactly 100 square millimeters. Multiply by 100 to increase resolution.
