How to calculate calories in Soy milk

Multiply the calories per 100 g by your portion weight, then divide by 100. For the reference 243 g portion, the calculation is:

54 × 243 ÷ 100 ≈ 131 kcal

Reference portion: cup (243 g). This is an example amount, not a recommended portion. Weigh your food when possible: a cup, slice or piece can vary in size.

Check that the entry matches the food you have, including its preparation. If raw or cooked is not specified, check your label or a matching nutrition reference before logging it.
