Unit list
These are the tokens the evaluator recognises after a number, in the
unit slot of an answer, or inside to(..., "unit"). Anything
compound is written as a product or quotient of them —
kN/m for a line load, N/mm^2 for a stress.
Tokens are case-sensitive: t is the tonne and
T the tesla. For how to type and pin units, see
Units,
conversion with to(), and
SI / USCS / CGS.

Tokens that catch people out
| Token | What it means |
|---|---|
gm and gr | Gram and grain. gr is not shorthand for gram. |
in and inch | Both give the inch, so use whichever reads better in the expression. |
mm2 m3 s2 | Squared and cubed forms exist as tokens in their own right, which lets you write kg*m/s2 without an exponent. |
degC degF degR K | The temperature scales. Type the deg spelling; the unit editor shows it back as °C, °F or °R. |
rpm and rps | Cyclic frequency rather than angular velocity, so 60 rpm is 1 Hz. |
percent | Defined as 0.01, and typing 15% after a number works too. The percent folds into the magnitude, so 20% reports 0.2 and 12 in * 90% reports 10.8 in. |
