Frequently Asked Questions
Multiply the volume in fluid ounces by 29.5735, then multiply by the density of the substance. For water: grams = fl oz × 29.5735. Example: 8 fl oz × 29.5735 = 236.59 grams.
1 US fluid ounce of water weighs 29.5735 grams. For milk it's about 30.46g, for oil about 27.21g, and for flour only about 15.65g.
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.
