How this conversion works
Recipes, coffee ratios, parcel postage and jewellery all live in the grams-to-ounces gap. Type either side: grams become ounces, ounces become grams, live.
Watch the one trap on this page: the weight ounce here (avoirdupois) is not the fluid ounce of volume, and neither is the troy ounce used for gold (31.1034768 g). For liquids, the ml to fluid ounces converter is the right page.
The exact formula
ounces = grams ÷ 28.349523125
1 oz = 28.349523125 g exactly (one sixteenth of the 0.45359237 kg pound). The reverse is grams = ounces × 28.349523125.
