Correct. Let’s show you an example of it in practice, before seeing if you can do it on your own!

Example: INSULIN To Carb Ratio of 1 units of insulin : For Every 15 Carbs consumed. (ICR 1:15) with the following meal (click to see how much carbs in each)

  • 36 grams of carbs (estimated)

  • 39g total carbs (estimated)

  • 32 grams of carbs (estimated)

1 slice of pizza + 1 soda

+ 2 scoops of ice cream =

36 grams of carbs + 39 grams of carbs

+ 32 grams of carbs (sugar) =

107 grams of carbs

107 divided by 15 [our ICR number] is 7.133 so the amount to take would be 7 units!

In most cases, you may have to round!
