You can see the full list of units currently accepted by LON-CAPA
by clicking on the small blue question-mark symbol that appears
whenever you get a response that the units you entered were not
understood by the program. The following table is adapted from the
LON-CAPA help file. Only units given in this table can be used, and
only the **symbols** shown can be used when entering the units.
For example, you must use "35 kg", not "35 kilograms".
(*Correct usage is also expected on exams and quizes.*)

Products and powers must be entered in a way that the computer can
understand. In addtion, the precedence of operations must be honored.
Two common examples would be "kg*m/s^2" and "J/(g*K)".
The last one could also be written as "J/g/K".
(*Once again, correct usage is also expected on exams and quizes.*)

The coded units are interpreted in the order of basic unit,
derived unit, then prefix.
For example, "min" will match "minutes" instead of
being treated as a combination of the prefix "m" and the
unit "in".
Further, "T" by itself will always be matched against
"tesla" instead of considered shorthand for 10^{12}
(which would be improper usage in any case).
