Enter the total carbohydrates (g) and the total insulin (g) into the Calculator. The calculator will evaluate the Carbohydrate To Insulin Ratio. 

Carbohydrate To Insulin Ratio Formula

CIR = C / I

Variables:

  • CIR is the Carbohydrate To Insulin Ratio (g/g)
  • C is the total carbohydrates (g)
  • I is the total insulin (g)

To calculate Carbohydrate To Insulin Ratio, divide the amount of carbohydrates by the total insulin.

How to Calculate Carbohydrate To Insulin Ratio?

The following steps outline how to calculate the Carbohydrate To Insulin Ratio.


  1. First, determine the total carbohydrates (g). 
  2. Next, determine the total insulin (g). 
  3. Next, gather the formula from above = CIR = C / I.
  4. Finally, calculate the Carbohydrate To Insulin Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total carbohydrates (g) = 200

total insulin (g) = 5
