# 2.1 BASE UNITS
#
# SI has a base of seven dimensions
#
dimensions 7
#
# Table 1
#
base	m			# length			metre
base	g			# mass				gram(*)
base	s			# time				second
base	A			# electric current		ampère
base	K			# thermodynamic temperature	kelvin
base	mol			# amount of substance		mole
base	cd			# luminous intensity		lumen
#
# *) SI wants kg instead of g as base unit for mass, yet, we
# require bases to be atoms
#

#
# 2.2 SUPPLEMENTARY UNITS
#
# radian and steradian for plain and solid angle are `supplementary'
# of dimension 1.
#
# Table 2
#
rad   = 1 1		 metric	# plain angle			radian
sr    = 1 1		 metric	# solid angle			streadian

#
# 2.3 DERIVED UNITS

J     = 1 N.m		 metric	# energy, work,			joule
				# quantity of heat
W     = 1 J/s		 metric	# power				watt

				# magnetic flux
T     = 1 Wb/m2		 metric	# magnetic flux density		tesla
				# magnetic induction
H     = 1 Wb/A		 metric	# inductance			henry
°C    = cel(1 K)      nonmetric	# Celsius temperature		degree Celsius
