Pythom utilities for working with Weights and Measures.
Wherever possible, wamu attempts to maintain the precision of a conversion as opposed
to relying on floating point math. For example, converting from meters per second to
kilometers per hour would be calculated as:
kmph = (mps * 3600.0) / 1000.0
However, the floating point division may result in loss of precision. In such cases,
wamu will simplify the expression to:
kmph = mps * 3.6
