How many millimeters are in a centimeter?

One centimeter equals exactly 10 millimeters.

When should I use centimeters instead of millimeters?

Centimeters are often easier to read for larger objects, while millimeters are preferred when greater precision is required.

Yes. Dividing 75 millimeters by 10 gives 7.5 centimeters.

1 Millimeter = 0.1 Centimeter

Millimeter (mm)

Centimeter (cm)

0.1

1 Millimeter = 0.1 Centimeter

1 Millimeter = 0.1 Centimeter. To convert millimeters to centimeters, multiply by 0.1.

5 mm × 0.1 = 0.5 cm

Result: 5 Millimeter = 0.5 Centimeter

Millimeters and centimeters are closely related and are often displayed together on rulers, measuring tapes and technical drawings.

Millimeters are useful when very small differences matter. Engineers, machinists and product designers frequently work in millimeters.

Centimeters provide a simpler way to describe larger measurements without creating long numerical values.

A smartphone may be listed as 150 millimeters tall, which is the same as 15 centimeters.

Divide millimeters by 10. For example: 120 mm = 12 cm 350 mm = 35 cm
