Maybe couple to pint:
import pint
ureg = pint.UnitRegistry()
# [E] = M L^2 T^-3 I^-1
E_pint = 1 * E_unitDim[api.Unit_Dimension.L] * ureg.m + \
E_unitDim[api.Unit_Dimension.M] * ureg.kg + \
E_unitDim[api.Unit_Dimension.T] * ureg.s + \
E_unitDim[api.Unit_Dimension.I] * ureg.A + \
E_unitDim[api.Unit_Dimension.theta] * ureg.K + \
E_unitDim[api.Unit_Dimension.N] * ureg.mol + \
E_unitDim[api.Unit_Dimension.J] * ureg.cd
# length L, mass M, time T, electric current I, thermodynamic temperature theta, amount of substance N, luminous intensity J
E_pint.check('[length]')
# False
E_pint.check('[length] * [mass] / [current] / [time]^3')
# True
E_pint.check('V/m')
# True
E_x.dimensionality
# <UnitsContainer({'[current]': -1.0, '[length]': 1.0, '[mass]': 1.0, '[time]': -3.0})>
# ^-- access just like a regular dictionary
# create:
pint.context.UnitsContainer({'[current]': -1.0, '[length]': 1.0, '[mass]': 1.0, '[time]': -3.0})
# <UnitsContainer({'[current]': -1.0, '[length]': 1.0, '[mass]': 1.0, '[time]': -3.0})>
A new, simple, step-by-step "first steps" section with detailed instructions. Cheat-sheet like.
