<p>Defines the conversion factor from a base unit to any unit or to another base unit with the correct dimensions. Uses of this macro must appear at global scope. If the destination unit is a base unit or a unit that contains only one base unit which is raised to the first power (e.g. feet->meters) the reverse (meters->feet in this example) need not be defined explicitly. </p>
