About Metre and Decimetre
The metre is the SI base unit of length, defined as the distance light travels in 1/299,792,458 of a second. It underpins the whole metric system and is used for rooms, fabric, sports fields and scientific work worldwide.
A decimetre is one-tenth of a metre, or 10 centimetres. It is rarely used in daily life but appears in science — a cubic decimetre is exactly one litre.
Both the Metre and the Decimetre are metric units, so converting between them is just a change of scale: one Metre equals 10 Decimetres, and the Metre is the larger unit.
