Where this conversion shows up
American recipes, supplement scoops and coffee dosing guides give weights in ounces that most kitchen scales (and the rest of the world) express in grams. Note this page is about weight — fluid ounces, the volume unit on drink cans, are a different animal entirely.
Worked example
A US recipe wants 4 oz of butter: 4 × 28.3495 = 113.4 g — exactly one US stick of butter, which is the easiest way to remember the factor. An 18 g espresso dose runs the other way: about 0.63 oz.
Rounding and precision
Round to the nearest gram for cooking; baristas and bakers often want tenths of a gram, which is why 0.1 g scales are standard coffee gear. Anchor values: 1 oz = 28.35 g, 8 oz = 226.8 g, 16 oz (1 lb) = 453.6 g.
