Ounces to grams multiplies by 28.349523125. A 4 oz burger patty is 113.4 g; a 16 oz (1 lb) steak is 453.6 g. Watch the units: fluid ounces are a volume measure (29.57 mL in the US, 28.41 mL in the UK), not a weight — converting fluid oz to g via this factor only works for water and gives wrong answers for flour, milk, or oil. For dry baking, ounces-by-weight is the only consistent reading.
Coffee roasters and precious-stone jewellers both depend on this exact figure daily — a 12 oz bag of beans is 340.19 g, a 0.5 oz gemstone parcel is 14.17 g, and a 4 oz espresso dose reference is 113.4 g. Digital jewellery scales sold for gem work often display both units live, but the internal calibration is grams, so a jeweller quoting "half an ounce" of stones is really working from a 14.17 g reading rounded up for the customer.

The avoirdupois ounce (oz) is a unit of mass in the imperial and US customary systems, defined as exactly 28.349523125 grams (1/16 of an avoirdupois pound). It is the standard small-mass unit in the United States for food packaging, recipes, and postal weights. Do not confuse it with the troy ounce (used for precious metals, 31.1035 g) or the fluid ounce (a volume).
The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is the everyday unit for food labeling, postage, jewelry, and laboratory measurements. The 2019 SI redefinition fixed the kilogram (and therefore the gram) in terms of Planck's constant, ending more than a century of dependence on a physical prototype.
