Convert Gram to Ounce (g → oz)

Converting grams to ounces is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in grams

   Start with the number of grams (g) you want to convert.
2. 2
   Multiply by 0.035274

   The conversion factor from g to oz is 0.035274. Multiply your value by this number.
3. 3
   Read the result in ounces

   The result is your value in ounces (oz).

Multiply the value in grams by 0.035274. For the reverse direction, multiply by 28.349523.

• ✓1 kitchen tablespoon of water weighs about 15 g, but 1 tablespoon of flour is only 8 g — density varies.
• ✓A kitchen scale reads to 1 g; a jewellery scale to 0.01 g.
• ✓Gold is priced by gram in Europe and per troy ounce in international markets.

• ✗Assuming a tablespoon of any ingredient equals 15 g — true only for water.
• ✗Confusing g (gram) with mg (milligram) on medication labels.
• ✗Using 28 g instead of 28.35 g when converting an ounce in precision baking.

What is the Gram?

The gram equals one thousandth of a kilogram (0.001 kg) and is the everyday metric unit for cooking ingredients, postage, jewelry, pharmaceuticals, and small product weights. Originally defined in 1795 as 'the absolute weight of a volume of pure water equal to a cube of one hundredth of a meter at the temperature of melting ice,' the gram is now formally defined via the kilogram. It relates simply to the milligram (1,000 mg = 1 g) and the kilogram (1,000 g = 1 kg). European nutrition labels universally use grams for ingredient quantities, and recipes worldwide outside North America measure ingredients by mass in grams rather than by volume. Gold and silver are traded in grams for small quantities, while gemstones use carats (0.2 g = 1 carat). A standard paper clip weighs about 1 g.

What is the Ounce?

The ounce equals exactly 28.349523125 grams or 1/16 of a pound. The word derives from the Latin 'uncia,' meaning one twelfth (the original Roman ounce was 1/12 of a Roman pound). The modern avoirdupois ounce, used for everyday weights in the United States and the United Kingdom, replaced the older Tower and Troy systems. It is the standard unit for American kitchen recipes (where 'ounce' refers to weight, distinct from the fluid ounce of volume), postal rates, package sizes (a 12-oz can of soda), and boxing-glove weights. Precious metals like gold and silver use the troy ounce (31.103 g), about 10% heavier than the avoirdupois ounce. The ounce relates to the pound (16 oz = 1 lb), the gram (1 oz ≈ 28.35 g), and the grain (1 oz = 437.5 grains).
