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 insulation coefficient is the RSI. All units of insulation coefficient 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 RSI -> Clo = 64.516129
convert(10; rsi; clo) = 64.516129
10 rsi -> rValue = 56.782633
convert(10; RSI; RValue) = 56.782633
10 RSI -> Tog = 100
convert(10; rsi; tog) = 100
10 clo -> tog = 15.5
convert(10; clo; tog) = 15.5
10 tog -> clo = 6.4516129
convert(10; tog; clo) = 6.4516129
10 rValue -> RSI = 1.7611018
convert(10; RValue; rsi) = 1.7611018
