Proposal for new chemical units #121
Description
IU - International Units
This unit is specified for common chemicals where you can't determine effectiveness by its absolute value. In those cases IU is used, which varies among each chemicals.
For example, micrograms are commonly used in most of vitamin drugs, but sometimes there's exceptions (such as milligrams). IU is the standardized relative unit.
kind: :unitless (I'm not sure)
aliases: [IU, international-units]
Eq - Molar Equivalent
kind: :substance (I'm not sure)
aliases: [Eq, molar-equivalent]
We have to make sure that prefixed unit is available for this unit, e.g. mEq.
Problem: You can't define a new unit which contains the % string.
I think this is related to the core parse routine, so I need your help on this.
v/v% - volume per volume
Specifies how much volume is contained in the substance.
kind: :unitless I guess. But if you are considering to create a new kind, :percentage, it might be more appropriate to use that one instead.
aliases: v/v%
definition: RubyUnits::Unit.new("1 mL") / RubyUnits::Unit.new("100 mL")
w/v% - weight per volume
Specifies how much weight is contained in the substance.
kind: same as v/v%.
definition: RubyUnits::Unit.new("1 g") / RubyUnits::Unit.new("100 mL")
