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 luminous intensity is the candela. All units of luminous intensity 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 candela -> bougie = 9.9157164
convert(10; candela; bougie) = 9.9157164
10 candela -> carcel = 1.026694
convert(10; candela; carcel) = 1.026694
10 candela -> hefner = 11.074197
convert(10; candela; hefner) = 11.074197
10 candela -> violle = 0.4957858
convert(10; candela; violle) = 0.4957858
10 violle -> candela = 201.7
convert(10; violle; candela) = 201.7
10 hefner -> candela = 9.03
convert(10; hefner; candela) = 9.03
10 carcel -> candela = 97.4
convert(10; carcel; candela) = 97.4
10 bougie -> candela = 10.085
convert(10; bougie; candela) = 10.085
10 carcel -> violle = 4.8289539
convert(10; carcel; violle) = 4.8289539
