Conversions can be done either with the "->" conversion operator or with the equivalent "convert" function. The function has three parameters: a quantity, a unit to convert from and a unit to convert to. Likewise the conversion operator uses three values: the quantity and unit to convert from are placed on the left side of the operator while the unit to convert to goes to the right side.
The basic unit of power is the watt. All units of power are expressed in terms of this base unit and so measurements can be converted from any one of the following units to any other.
10 watt -> horsepower = 0.0134102
convert(10; watt; hp) = 0.0134102
10 watt -> btuPH = 34.121416
convert(10; watt; btuPH) = 34.121416
10 watt -> clusec = 7,501,875.5
convert(10; watt; clusec) = 7,501,875.5
10 watt -> lusec = 75,018.755
convert(10; watt; lusec) = 75,018.755
10 horsepower -> watt = 7,456.9987
convert(10; horsepower; watt) = 7,456.9987
10 lusec -> watt = 0.001333
convert(10; lusec; watt) = 0.001333
10 statWatt -> watt = 0.000001
convert(10; statWatt; watt) = 0.000001
10 btuPS -> HP = 14.148532
convert(10; btuPS; horsepower) = 14.148532
10 statWatts -> clusecs = 0.7501875
convert(10; statWatt; clusec) = 0.7501875
10 hp -> btuPS = 7.067871
convert(10; horsepower; btuPS) = 7.067871
10 horsepower -> btuPH = 25,444.336
convert(10; HPs; btuPHs) = 25,444.336
