woo._units

Woo is internally unit-agnostic (using SI units is highly recommended). This module defines conversion multipliers for various units; values of multipliers are taken from c++ sources.

The unit map is exposed as woo.unit, so that expressions like 16*woo.unit['deg'] can be used in python.

woo._units.baseUnit = {'%': '-', '-': '-', 'GPa': 'Pa', 'J/m²': 'J/m²', 'MN': 'N', 'MN·m': 'N·m', 'MPa': 'Pa', 'Mt/y': 'kg/s', 'N': 'N', 'N·m': 'N·m', 'N·m·s': 'N·m·s', 'Pa': 'Pa', 'cm': 'm', 'day': 's', 'deg': 'rad', 'g': 'kg', 'g/cm³': 'kg/m³', 'in': 'm', 'kN': 'N', 'kN·m': 'N·m', 'kPa': 'Pa', 'kg': 'kg', 'kg/m³': 'kg/m³', 'kg/s': 'kg/s', 'kg·m²': 'kg·m²', 'km/h': 'm/s', 'm': 'm', 'm/min': 'm/s', 'm/s': 'm/s', 'm/s²': 'm/s²', 'mm': 'm', 'mm²': 'm²', 'mm³': 'm³', 'ms': 's', 'm²': 'm²', 'm³': 'm³', 'ppm': '-', 'rad': 'rad', 'rad/s': 'rad/s', 'rot/min': 'rad/s', 'rot/s': 'rad/s', 'rph': 'rad/s', 'rpm': 'rad/s', 's': 's', 't': 'kg', 't/h': 'kg/s', 't/m³': 'kg/m³', 't/y': 'kg/s', 'year': 's', 'μs': 's', '‰': '-'}
