About grams and ounces
The avoirdupois ounce
The standard ounce used in the US and UK for everyday weight (food, mail, body weight, household goods) is the avoirdupois ounce. 1 avoirdupois ounce = 28.3495 g exactly. There are 16 avoirdupois ounces in 1 pound, and the pound is exactly 0.45359237 kg by international agreement.
Don't confuse with troy ounce
Precious metals (gold, silver, platinum) use the troy ounce, which is heavier: 1 troy ounce = 31.1035 g. So a "1 ounce gold coin" weighs 31.1 g, not 28.3 g. The 10 percent difference matters enormously in gold trading. This calculator uses the standard avoirdupois ounce; for gold weights use our Tola to Grams calculator (Tola is 11.6638 g and is the South Asian gold unit).
Cooking conversions
Convert recipes between metric (grams) and US (ounces) with this calculator. Common kitchen conversions: 1 oz = 28 g, 2 oz = 57 g, 4 oz = 113 g, 8 oz = 227 g, 16 oz (1 lb) = 454 g. Most professional bakers use grams for precision; cup measurements vary by how packed an ingredient is.
Nutrition labels
European nutrition labels use grams per 100 g, while US labels often use ounces per serving. Convert between them to compare. A typical serving of protein on a US label (about 3 oz) equals 85 grams on a European label.
Divide grams by 28.3495 to get ounces. So 100 g = 3.527 oz, and 500 g = 17.64 oz. For mental math, divide by 28 (slight over-estimate).
1 ounce (oz, the avoirdupois ounce used in US recipes and shipping) = 28.3495 g. For most cooking purposes, 28 g is close enough.
8 oz = 226.8 g. That is the standard size of a small block of cream cheese or a US "cup" of liquid measured in fluid ounces (8 fl oz = 237 mL, slightly different).
100 g = 3.527 oz, or about 3.5 oz. A common food serving size, especially for protein.
Yes. The troy ounce (used for precious metals: gold, silver, platinum) is 31.1035 g. The regular avoirdupois ounce (used for food, mail, body weight) is 28.3495 g. The calculator uses the avoirdupois ounce.
The ounce was originally defined as 1/16 of a pound, and the pound was defined relative to British weight standards centuries before the metric system existed. The exact factor of 28.3495 g is the modern definition of the avoirdupois ounce.
The factor 28.3495 g per ounce is the standard avoirdupois definition. Results show 6 significant figures, more than any kitchen scale or food label would use.
16 oz (1 pound) = 453.59 g. The pound is the foundation of the US weight system; an ounce is 1/16 of a pound.
Common kitchen weights: 1 oz = 28.35 g, 2 oz = 56.7 g, 4 oz = 113.4 g, 8 oz (1/2 lb) = 226.8 g, 16 oz (1 lb) = 453.6 g. Round to 30, 60, 115, 225, 450 for fast mental math.
Grams are precise, especially for baking. Ounce measurements use round numbers but a US ounce of flour by weight differs from a fluid ounce by volume. Many bakers prefer the precision of grams.
