# Unit description table
#
# Each line consitsts of
#
# name     mode     definition
#
# Here, mode is S, P, or N:
#
# S: the unit is in the sigular form only (does not take the plural form),
#    and it can be prefixed. (such as A --> mA etc.)
# P: the unit can take the plural form (such as second --> seconds).
#    Prefixes are not allowed.
# N: same as S, but the unit cannot be prefixed (thus it is used only
#    in the original form).
