Simple MKS units library in Python (designed for 3.0+).
This library is an attempt to produce a simple yet robust unit library, using a technique inspired by OpenFOAM's type checking. The library keeps a 7-vector component for the power of each of the SI base units.
Consider the following example: >>> from mks_units import * >>> x = Unit(5, "mm") >>> y = Unit(5, "m s^-1") >>> "%s" % (x*y) '0.025000 m^2 s^-1'
Units can be passed as a space-separated list of valid units to numeric powers.
Internally, mks_units converts all types to powers of the SI base units, but
can convert back fairly easily:
>>> "{0:1.5f in^2 min^-1}.format(xy)
'2325.00465 in^2 min^-1'
>>> (xy).value_as("in^2 min^-1")
2325.0046500093003
mks_units supports all meaninful math functions.
Additional units can be added to mks_units.UNITS to facilitate additional
applications.
