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
```
