CAPA units

Examples of correct use of units:

• Speed has units of m/s or mi/hr or ft/min, etc.
• Acceleration has units of m/s^2 or ft/min^2, etc.
• Volume has units of m^3 or cm^3 or in^3 or even m*m*m, etc.
• Force has units of newtons; capa will accept either N or kg*m/s^2.
• Work has units of joules (1 joule = 1 newton meter); capa will accept J or N*m or kg*m^2/s^2.
• When constructing units, multiplication = *, division = /, and raising to a power = ^.
