Formula and notes
1 centimetre = 10 millimetres; conversely, 1 millimetre = 0.1 centimetres.
The converter uses the base unit method: centimetre has a factor of 0.01 and millimetre has a factor of 0.001, so the target value = source value × (0.01 ÷ 0.001).
Length and area converters use exact international definitions, so results are consistent across calculators.
