About this conversion
This Koverts page converts millimeters (mm) to centimeters (cm) — one of the most common metric length steps on rulers, 3D printing, and engineering drawings.
The millimeter (mm) is 1/1000 of a meter. It is used for precise tolerances, jewelry thickness, rainfall amounts, and 3D printer layer heights.
The centimeter (cm) is 1/100 of a meter. It is the everyday unit on school rulers, body measurements, and many product dimensions outside the US.
Typical uses
- Ruler and homework: mm columns on metric rulers
- 3D printing: layer height and model scale
- Rainfall and precipitation reports
- Engineering tolerances and sheet metal thickness
Common reference values
- 1 mm = 0.1 cm
- 10 mm = 1 cm
- 100 mm = 10 cm
Tip: Divide millimeters by 10 to get centimeters. So 25 mm ÷ 10 = 2.5 cm.
Did you know? The metric prefix ‘milli-’ always means one thousandth — so remembering mm→cm is the same pattern as mL→L or mg→g.
Educational reference - always verify critical measurements (medical, engineering, legal) with primary sources.
