1 cm² ≈ 100 mm²
Precision changes displayed rounding, not calculation accuracy.
mm² = cm² × 100mm² = cm² × 100
Multiply the cm² reading by 100.
1 cm² ≈ 100 mm²
1 × 100 ≈ 100
10000 cm² ≈ 1000000 mm²
10000 × 100 ≈ 1000000
Area factors scale with the square of the length factor. For example, 1 ft = 0.3048 m gives 1 ft² = 0.3048² m² = 0.09290304 m².
