Decimetre (dm)
The decimetre (symbol dm) is a metric unit of length equal to one tenth of a metre, or 10 centimetres. While less commonly cited for linear measurement in daily language than the centimetre or metre, the decimetre serves as a critical structural link in the SI system because one cubic decimetre precisely defines the standard litre. Derived directly from the metric reform during the French Revolution, it remains useful in engineering and chemistry.
