The three ratios used when carbohydrate counting are listed below. 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
