How D-SI Units Are Composed
D-SI units are represented as strings where each component is preceded by a backslash (\).
A basic D-SI unit string is composed of:
- An optional prefix (e.g.
\kilo for 10³, \milli for 10⁻³),
- A base unit (e.g.
\metre, \second),
- An optional exponent specified with
\tothe{...} (e.g. \metre\tothe{2} for square metre),
with fractional exponents like 0.5, 0.333333, or 0.25 rendered as square, cube, or fourth roots respectively.
- An optional fraction operator
\per is used to combine units into a fraction (e.g. \metre\per\second for metres per second).
Use the auto-complete input below to type a D-SI string. After typing a backslash and at least one letter,
suggestions will appear based on the allowed tokens. When the field loses focus, the rendered unit is shown (while
the raw string is preserved for further editing when focused again). External suggestion lists can also be provided.
