Units

Some reading about units:

• Metrology
• SI system
• Imperial units
• SI derived units
• angle units
• unit implemented in OCC

Examples

# -- some examples of the LabRPS unit translation system --
# make a shortcut for the examples
pq = LabRPS.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')/tu('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') / tu('gon')

# more imperial
tu('1ft (3+7/16)in')

# or 
pq('1\' (3+7/16)"') # the ' we have to escape because of python

# trigonometry
pq('sin(pi)')
