The three ratios used when carbohydrate counting are listed below.

Blood Sugar / Insulin  ratio { BG/I }
the number of blood sugar points lowered by a unit of insulin

Carbohydrate / Insulin  ratio { CARB/I }
the amount of carbohydrate required for each unit of insulin

Blood Sugar / Carbohydrate  ratio { BG/CARB }
the number of blood sugar points raised by one gram of carbohydrate
Any two of the ratios that are known can be used to calculate the remaining
ratio.
However, it is more informative to use all three known and measured values
to calculate what the ratios should be based on their mathematical
relationship
to one another. This will tell you how far off the values are that you
use
on a day to day basis.
The ratios have a FIXED mathematical relationship to each other
as follows:
Blood Sugar BG CARB BG
to  =  X 
Insulin ratio I I CARB
Carbohydrate CARB BG / I
to  = 
Insulin ratio I BG / CARB
Blood Sugar BG BG / I
to  = 
Carbo ratio CARB CARB / I
