How to convert millimetres to centimetres
Multiply the number of millimetres by 0.1. That is the whole calculation: cm = mm × 0.1. To go back the other way, divide instead, or multiply by 10.
Worked example: 12 millimetres × 0.1 = 1.2 centimetres.
Where this conversion comes up
Length conversions show up constantly in printing, DIY, engineering drawings and anything bought from a country using the other measurement system. If you are converting in order to set a page or grid size, the graph paper generator accepts spacing in millimetres directly, and the on-screen ruler lets you check a printed result against both scales.
