Multiply the number of Millimeters by 0.1 to get Centimeters. Formula: cm = mm × 0.1. Example: 10 mm × 0.1 = 1 cm. To reverse, divide Centimeters by 0.1 to get Millimeters.
| Millimeter (mm) | Centimeter (cm) |
|---|---|
| 0.001 mm | 0.0001 cm |
| 0.01 mm | 0.001 cm |
| 0.1 mm | 0.01 cm |
| 0.5 mm | 0.05 cm |
| 1 mm | 0.1 cm |
| 2 mm | 0.2 cm |
| 5 mm | 0.5 cm |
| 10 mm | 1 cm |
| 20 mm | 2 cm |
| 50 mm | 5 cm |
| 100 mm | 10 cm |
| 250 mm | 25 cm |
| 500 mm | 50 cm |
| 1000 mm | 100 cm |
| 10000 mm | 1000 cm |
To convert Millimeter to Centimeter, multiply by 0.1. Example: 10 mm = 1 cm
To convert Centimeter back to Millimeter, divide by 0.1 (multiply by 10). Use the swap button above.
Start with 100 Millimeters = 10 cm as your reference point. Scale up or down from there.
ISO engineering drawings specify all dimensions in millimetres while reference data and overview dimensions are sometimes expressed in centimetres. Engineers and machinists convert between mm and cm constantly in production and quality control.
Tumour sizes in oncology are measured in millimetres on imaging reports while patient records and clinical summaries use centimetres for the same measurement. Clinicians convert between mm and cm in every patient consultation and report.
Rain gauges are calibrated in millimetres for precise daily measurement while monthly and annual totals use centimetres. Meteorologists and hydrologists convert between mm and cm throughout weather analysis and climate reporting.
Fabric thickness and thread diameter use millimetres while garment dimensions and pattern pieces use centimetres. Fashion designers and textile engineers convert between mm and cm for every material specification and garment construction detail.
Paediatric growth velocity is tracked in mm per month for clinical precision while height charts use centimetres for scale and readability. Paediatricians convert between mm and cm in every growth assessment consultation.
Lens focal lengths use millimetres (50mm lens) while sensor dimensions and print sizes use centimetres. Photographers, optical designers, and printers convert between mm and cm for every lens selection and print sizing calculation.
The Millimeter is a unit of Length measurement (symbol: mm). 1 mm = 0.1 cm. Used in scientific and practical Length measurement applications.
The Centimeter is a unit of Length measurement (symbol: cm). It is part of an internationally recognised measurement system used alongside the Millimeter.
The millimetre was introduced alongside the metre in 1795 as part of the French metric system — one-thousandth of a metre, from the Latin 'mille' (thousand). Its practical importance emerged during the Industrial Revolution, when manufacturing tolerances first needed sub-centimetre precision. By the 20th century, ISO engineering drawing standards adopted millimetres as the primary dimension unit for all technical drawings worldwide. Today millimetres are the universal language of engineering — from the finest watch gear to the largest aircraft fuselage — and are the most widely used length unit in global manufacturing.
The centimetre was introduced in 1795 as part of the French metric system — one-hundredth of a metre, from the Latin 'centum' (hundred). The CGS system built around it became dominant in 19th-century science and remains standard in astrophysics today. The centimetre is now the primary unit for body measurements, clothing sizes, and everyday objects in most of the world.
Common use: Millimeter to Centimeter conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
