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
