The following subsections show the physical units that LON-CAPA accepts.
The symbols must be used when entering the units, for example {}``35 kg''.
-Note that compound units are formed by using *, / and ^. For example, an acceleration might
-be in terms of ``m/s^2'' or meters per second squared. This could also be expressed as``m/s/s''.

Units of Newton-meters (for torque) would be entered as ``N*m''. Parentheses may be used to guarantee
the correct sense of the unit. Kilometers per Ampere-hour could be written as ``km/(A*hr)'' or
``km/A/hr'' but not ``km/A*hr''. The last option would be interpreted as kilometer times hours per Ampere.
