Insulin to Carb Ratio Calculator

What is the Insulin to Carb Ratio?

The Insulin to Carb Ratio (ICR) is a measure that helps people with diabetes determine how many carbohydrates affect their blood sugar levels. It's calculated by dividing the number of insulin units by the grams of carbohydrates consumed.

How to Use This Calculator

1. Enter the total grams of carbohydrates you plan to consume in the "Total Carbohydrates" field.
2. Enter the number of insulin units you plan to take in the "Insulin Units" field.
3. Click the "Calculate" button to determine your ICR.
4. The result will be displayed as "units per gram" of carbohydrates.

Example Calculation

If you plan to eat 30 grams of carbohydrates and take 5 units of insulin, your ICR would be:

5 units / 30 grams = 0.17 units per gram

This means that for every gram of carbohydrate you eat, your blood sugar will increase by approximately 0.17 units.

Using Your ICR

Once you know your ICR, you can use it to calculate how much insulin to take before meals. For example, if your ICR is 0.17 and you plan to eat 60 grams of carbohydrates, you would take:

60 grams × 0.17 units/gram = 10.2 units of insulin

Important Notes

• Your ICR may vary based on factors such as your age, weight, activity level, and diabetes medications.
• It's important to discuss your ICR with your healthcare provider to determine the appropriate amount of insulin to take before meals.
• Always carry a source of fast-acting glucose in case your blood sugar drops too low.
