parmed.unit.Unit

class parmed.unit.Unit(base_or_scaled_units)

Physical unit such as meter or ampere.

Methods

conversion_factor_to(other)	Returns conversion factor for computing all of the common dimensions between self and other from self base units to other base units.
create_unit(scale, name, symbol)	Convenience method for creating a new simple unit from another simple unit.
get_conversion_factor_to_base_units()	There may be ScaleUnit components to this Unit.
get_name()	Returns a unit name (string) for this Unit, composed of its various BaseUnit symbols.
get_symbol()	Returns a unit symbol (string) for this Unit, composed of its various BaseUnit symbols.
in_unit_system(system)	Returns a new Unit with the same dimensions as this one, expressed in a particular unit system.
is_compatible(other)	Returns True if two Units share the same dimension.
is_dimensionless()	Returns True if this Unit has no dimensions.
iter_all_base_units()	Yields (BaseUnit, exponent) tuples comprising this unit, including those BaseUnits found within ScaledUnits.
iter_base_dimensions()	Yields (BaseDimension, exponent) tuples comprising this unit.
iter_top_base_units()	Yields (BaseUnit, exponent) tuples in this Unit, excluding those within BaseUnits.
sqrt()	Returns square root of a unit.
