How to calculate calories in Pesto
Multiply the calories per 100 g by your portion weight, then divide by 100. For the reference 16 g portion, the calculation is:
418 × 16 ÷ 100 ≈ 67 kcal
Reference portion: tablespoon (16 g). This is an example amount, not a recommended portion. Weigh your food when possible: a cup, slice or piece can vary in size.
