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.
