How it's calculated
fl oz = g ÷ (density × 29.5735)
g = grams, density = g/mL (water 1.00, honey 1.42, oil ≈ 0.92), 29.5735 = mL per US fluid ounce. Reverse: g = fl oz × density × 29.5735.
Common values
| Ingredient | 100 g | Fluid ounces |
|---|---|---|
| Water | 100 g | 3.38 fl oz |
| Honey | 100 g | 2.38 fl oz |
| Olive oil | 100 g | 3.69 fl oz |
Common questions
Why isn't 100 g always the same number of fluid ounces?
Grams measure weight and fluid ounces measure volume. Denser ingredients like honey take up less space per gram, so they convert to fewer fluid ounces.
Is this US or UK fluid ounces?
It uses the US fluid ounce.
