Converting Centimetres to Millimetres.In design we either use mm (millimetres) or m (metres) to measure objects, we do not use cm (centimetres). This is because architects, engineers, car designers, graphic designers and builders only use millimetres and centimetres.

10mm = 1cm so 25mm will equal 2.5cm (just divide or times by 10, or move the decimal point).Remember, mm are smaller than cm, so if you are converting mm the number should get bigger (it’s as simple as adding 0).
