How to Convert 20 Grams to Fluid Ounces
The conversion from grams to fluid ounces requires knowing the substance's density because grams measure mass while fluid ounces measure volume.
Fluid Ounces = Grams ÷ (Density × 29.5735) Step-by-Step Example: 20g of Water
- Identify the density: Water = 1.0 g/mL
- Apply the formula: 20 ÷ (1.0 × 29.5735) = 20 ÷ 29.5735
- Calculate: = 0.6763 US fluid ounces
Why Density Matters
100 grams of flour occupies about 6.39 fl oz of space, while 100 grams of honey only fills 2.38 fl oz. The same weight of different substances occupies very different volumes.

Frequently Asked Questions
Divide the mass in grams by the density of the substance (in g/mL), then divide by 29.5735. For water (density = 1.0 g/mL), simply divide grams by 29.5735. Example: 100g ÷ 29.5735 = 3.3814 fl oz.
No. Grams (g) measure mass (weight), while fluid ounces (fl oz) measure volume. Converting between them requires knowing the density of the substance. Only for water does 1 gram equal approximately 1 mL.
Because grams measure weight and fluid ounces measure volume. Different substances weigh different amounts per unit of volume. For example, 100g of flour takes up much more space (6.39 fl oz) than 100g of honey (2.38 fl oz).
100 grams of water equals 3.3814 US fluid ounces. For other substances: 100g milk = 3.28 fl oz, 100g oil = 3.68 fl oz, 100g flour = 6.39 fl oz.
