Interface Dimension

public interface Dimension
Represents the physical dimension of a quantity.

A dimension is defined by the exponents of the seven SI base dimensions: Length (L), Mass (M), Time (T), Electric Current (I), Temperature (Θ), Amount of Substance (N), and Luminous Intensity (J).

Dimensions enable dimensional analysis - checking that equations are dimensionally consistent. For example: 

Force = Mass × Acceleration
[F] = [M] × [L][T]⁻²
[F] = [M¹L¹T⁻²]
