Overview

You typically use instances of NSUnitConcentrationMass to represent specific quantities of concentration using the NSMeasurement class.

Concentration of Mass

Concentration is the abundance of a constituent within a volume. Concentration can be expressed by SI derived units in terms of kilograms per cubic meter (kg/m³).

The NSUnitConcentrationMass class defines its base unit as gramsPerLiter, and provides the following units, which are initialized using UnitConverterLinear converters with the specified coefficients:

Name	Method	Symbol	Coefficient
Grams Per Liter	`gramsPerLiter`	g/L	`1`
Milligrams Per Deciliter	`milligramsPerDeciliter`	mg/dL	`0.01`
Millimoles Per Liter	`millimolesPerLiter(withGramsPerMole:)`	mmol/L	`18 * gramsPerMole`
