public interface Quantity<Unit extends MeasurementUnit<Unit>> extends Comparable<Quantity<Unit>>, Serializable
A quantity with a numerical value with a MeasurementUnit.

Quantity or amount is a property that can exist as a multitude or magnitude, which illustrate discontinuity and continuity. Quantities can be compared in terms of "more", "less", or "equal", or by assigning a numerical value multiple of a unit of measurement. Mass, time, distance, heat, and angle are among the familiar examples of quantitative properties.
