Mass class

A mass Measurement - for example 55.67 grams.

To create a new Mass object, use any of this class's factory constructors. For example,

Mass heightOfEverest = Mass.fromKilograms(8.848);

Use one of the properties, such as inGrams, to retrieve the double value of the Mass in the specified mass unit. For example,

Mass heightOfEverest = Mass.fromKilograms(8.848);
assert(heightOfEverest.inGrams == 8848.0);

This class provides a collection of arithmetic and comparison operators.

See Measurement for the collection of arithmetic and comparison operators which this class provides.
