I:C ratio.

The number of units of insulin that must be administered to a patient to prevent the carbohydrates consumed during a meal from elevating blood glucose levels. Typical I:C ratios for adults are 1:12. Children, who are usually more active than adults, may need only 1 unit of insulin for every 25 g of carbohydrates they eat.
