Measurement systems 
The units of measure stated in this document are listed below: 
1 gamma = 1 nano tesla 
1 tesla = 10,000 gauss 
cm = in x 2.54 
Lb = kg x 2.2 
Degrees F = [°C x 1.8] + 32 
Degrees C = [°F - 32]/1.8 
u' = 4x/(-2x + 12y + 3) 
v' = 9y/(-2x + 12y + 3) 
x = (27u'/4)/[(9u'/2) - 12v' + 9] 
y = (3v')/[(9u'/2) - 12v' + 9] 
nits = cd/(m2) = Ft-L x 3.426 
lux = foot-candle x 10.76
