# The format of this file is as follows:
#
#
#   Units must be broken up into categories. Start each category
#   with the following line:
#
#       name units
#
#   where 'name' is the name of your category (e.g. SI or English).
#   Use no spaces in 'name' of your category.
#
#
#   Next, define all units within a category using:
#
#	unit[=expression] [excluded prefixes or 'constant']
#
#   Note that NO spaces can be used in the expression, before/after
#   the '=', or in the excluded prefixes.
#   The only spaces MUST be between the unit and the excluded prefixes (if there
#   are any excluded prefixes)
#
#   'constant' can be used in place of excluded prefixes in order to exclude
#   all prefixes.
#
#
#   Blank lines do not effect anything and everything following a '#'
#   is a comment.

SI units		# SI units include all standard units, and should
			#    never be unassigned.

s
			# This is a bit of a trick to make 'kg' standard instead of 'g'.
g=(0.001*kg) k		#    defines g, ng, mg, Mg, etc., excluding kg, in terms of kg.
kg constant		#    protects kg (and only kg).
