Some reading about units:
# -- some examples of the FreeCAD unit translation system --
# make a shortcut for the examples
pq = FreeCAD.Units.parseQuantity
# 10 meters in internal numbers
pq('10 m')
# doing math
pq('3/8 in')
# combined stuff
pq('100 km/h')
# transfer to other units
pq('100 km/h') / pq('m/s')
# derived units (Ohm)
pq('m^2*kg*s^-3*A^-2')
# or
pq('(m^2*kg)/(A^2*s^3)')
# angles
pq('2*pi rad') # full circle
# as gon
pq('2*pi rad') / pq('gon')
# more imperial
pq('1ft (3+7/16)in')
# or
pq('1\' (3+7/16)"') # the ' we have to escape because of python
# trigonometry
pq('sin(pi)')
# Using translated units as parameters, this command will create a 50.8mm x 20mm x 10mm box
