# Oolong tea — Calories & Nutrition Facts

> Oolong tea has 31 calories per 100ml, with 0.1g protein, 7.91g carbs, and 0.15g fat — verified against official HPB Singapore data.

**Not the same number:** the 31 kcal above is per 100ml, and nobody orders 100ml. A standard HPB-recorded medium cup of Oolong tea is 500ml, which works out to approximately 155 kcal for the actual cup — don't combine the per-100ml figure with the whole-cup figure, they measure different serving sizes.
