Pro Tips for Weight Conversion
- Dry Weight vs. Fluid Volume: This tool converts weight (dry ounces). Do not confuse standard ounces (oz) with fluid ounces (fl oz), which measure liquid volume. 1 oz of flour and 1 fl oz of water are completely different measurements!
- The "Rule of 28": If you need to estimate quickly in your head, just multiply your ounces by 28 to get a close approximation in grams.
- Nutritional Label Rounding: You will often see nutritional labels round 1 ounce up to "30g" for simplicity. While acceptable for rough estimates, always use the exact 28.35g conversion for recipes and scientific calculations.
