About Decimetre and Metre
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.
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.
Both the Decimetre and the Metre are metric units, so converting between them is just a change of scale: one Decimetre equals 0.1 Metres, and the Metre is the larger unit.
