When you need to convert metre to millimetre

Length conversions come up constantly in DIY, travel and online shopping — sizing furniture, reading a height in a different system, or checking a screen or fabric measurement listed in unfamiliar units.

Typical values: 0.5 m is about 500 mm, and 5 m works out to roughly 5000 mm. Because the ratio is fixed at 1000, you can scale any amount linearly — doubling the metres doubles the millimetres.

Metric and imperial length units coexist worldwide, so the same object is often quoted two ways depending on the country.

How to convert metre to millimetre

One metre equals 1000 millimetres. To convert, multiply the number of metres by 1000:
