Enter the units of rapid-acting insulin and the grams of carbohydrates (g) into the Calculator. The calculator will evaluate the Insulin to Carb Ratio. 

Insulin to Carb Ratio Formula

ISCR = UI / C

Variables:

  • ISCR is the Insulin to Carb Ratio (units/g)
  • UI is the units of rapid-acting insulin
  • C is the grams of carbohydrates (g)

To calculate the Insulin to Carb Ratio, divide the units of rapid-acting insulin by the grams of carbohydrates.

How to Calculate Insulin to Carb Ratio?

The following steps outline how to calculate the Insulin to Carb Ratio.

  1. First, determine the units of rapid-acting insulin. 
  2. Next, determine the grams of carbohydrates (g). 
  3. Next, gather the formula from above = ISCR = UI / C.
  4. Finally, calculate the Insulin to Carb 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.

units of rapid-acting insulin = 5

grams of carbohydrates (g) = 70
