Frequently Asked Questions

How many centimeters are in a millimeter?

There are 0.1 centimeters in one millimeter (1 mm = 0.1 cm).

How do you convert 100mm to cm?

100 millimeters is equal to 10 centimeters (100 ÷ 10 = 10 cm).

Is 10mm equal to 1cm?

Yes, exactly. 10 millimeters equals 1 centimeter by definition in the metric system.

Why use centimeters instead of millimeters?

Centimeters are often more convenient for everyday measurements where millimeter precision isn't necessary, providing a middle ground between meters and millimeters.

What's bigger, 5mm or 1cm?

1 centimeter is bigger than 5 millimeters (1 cm = 10 mm, so 1 cm > 5 mm).
