decimetre
LowTechnical/Scientific
Definition
Meaning
A metric unit of length equal to one-tenth of a metre.
Used as a specific measurement in scientific and technical contexts; the cubic decimetre is a common alternative name for the litre in volume measurement.
Linguistics
Semantic Notes
A unit in the metric system (SI). While precise, it is less common in everyday speech than centimetres or metres. The cubic decimetre (dm³) is formally equivalent to the litre.
Dialectal Variation
British vs American Usage
Differences
Spelling: British English uses 'decimetre', American English uses 'decimeter'.
Connotations
None; purely technical unit in both varieties.
Frequency
Equally low-frequency in both UK and US technical/scientific writing; centimetre and metre are vastly more common in general use.

Examples
By Part of Speech
adjective
British English
- The decimetre ruler was used for the calibration.
American English
- We need a decimeter-scale model for the experiment.
Examples
By CEFR Level
- A ruler can show one decimetre.
- The box is about two decimetres long.

- The precision of the component required tolerances within a few tenths of a decimetre.
Learning
Memory Aids
Mnemonic
Think of a DECImeter as a tenth (like DECImal) of a metre. A typical adult handspan from thumb to little finger is roughly one decimetre.
Conceptual Metaphor
MEASUREMENT IS DIVISION (Part of a whole standard unit).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct cognate 'дециметр' (detsimetr) exists and has identical meaning, so risk is low. The spelling difference (re/er) should be noted.
Common Mistakes
- Misspelling as 'desimeter'.
- Confusing with 'decametre' (10 metres).
- Incorrectly capitalising as 'DeciMetre'.

Frequently Asked Questions
There are 10 centimetres in one decimetre.
No, it is a specialised term primarily used in scientific, engineering, or technical contexts. Centimetres and metres are far more common for everyday measurements.
The standard abbreviation is 'dm'.
They are equivalent. One cubic decimetre (dm³) is exactly equal to one litre (L).
