Convert centimetres to metres

One centimetre is 0.01 metres. To convert any amount, multiply by 0.01. Going the other way, one metre is 100 centimetres.

Multiply the centimetre figure by 0.01. So m = cm × 0.01. For a quick mental estimate, dividing by about 100 gets you close enough for most everyday purposes.

One centimetre is about the width of an adult fingernail. The centimetre is the everyday metric unit for body measurements and paper sizes, though it is not an SI-preferred prefix step — engineers tend to jump from millimetres to metres.

One metre is roughly the height of a kitchen counter plus a bit. The metre has been defined since 1983 as the distance light travels in a vacuum in 1/299,792,458 of a second — a definition that ties it to a physical constant rather than to any object.

Yes. Since the 1959 international yard and pound agreement, the imperial and metric systems are related by exact definitions rather than measurements — the inch is exactly 25.4 mm and the pound exactly 0.45359237 kg. Everything derived from those, including this conversion, is therefore exact. Round at the end rather than partway through, since rounding cm before converting introduces an error the conversion then multiplies.
