When you need grams to ounces

Metric recipes, coffee dosing, and postage are measured in grams; American recipes and US postal rates use ounces. 100 g of flour is about 3.53 oz, a typical 18 g coffee dose is about 0.63 oz, and a 250 g letter is about 8.8 oz.

These are ounces of weight (avoirdupois), not fluid ounces — a common mix-up in the kitchen. Fluid ounces measure volume, so 8 oz of flour by weight is not the same as 8 fl oz of flour in a measuring cup.
