Numerical Response problems can require units. In the problem editing form, place the desired unit in the Unit field. A complete list of units is in the Physical Units section (Help). The computer will accept the answer in any of its accepted unit formats. For example, if the answer to a problem is "1ft", the computer will accept "12in" as correct.

Additional units can be defined using the "customunits" parameter, which is a comma-separated list of unit conversions. For example


would define the new units peck, bushel, and gallon. The last entry in a conversion chain always needs to be a unit that LON-CAPA already supports.
