g to oz formula
Direct Answer: 1 g = 0.035273962 oz, so multiply by 0.035273962: oz = g × 0.035273962. Going back: g = oz × 28.349523.
How to convert grams to ounces
The avoirdupois ounce is 1/16 of a pound, exactly 28.349523125 grams. Dividing grams by that number, or multiplying by 0.035274, gives ounces. Precious metals use the heavier troy ounce (31.1035 g), which the main weight converter also covers.
1. g → oz
Multiply the number of grams by the conversion factor:
Example: 250 g × 0.035273962 = 8.82 oz.
2. oz → g
To go back, divide by the same factor, or multiply by its reciprocal, 28.349523:
Example: 8.82 oz ÷ 0.035273962 = 250 g.
Mental math: divide by 28
Divide the grams by 28. The estimate runs about 1% high, close enough for any recipe:
250 g: 250 ÷ 28 = 8.93 oz (exact: 8.82 oz).
