About grams and ounces
The avoirdupois ounce is one sixteenth of a pound, which makes it exactly 28.349523125 grams. Going the other way, a gram is 0.03527396 ounces. It is the ounce meant on food packaging, kitchen scales and postal rates.
Two other ounces exist and are easy to confuse with it. The troy ounce, used for precious metals, is 31.1035 grams, about 10% heavier, so a troy ounce of gold is not the same as an ounce of flour. The fluid ounce is not a weight at all but a volume, roughly 29.6 ml in the US and 28.4 ml in the UK. Recipes that switch between weight and fluid ounces without saying so are a common source of error; the volume converter handles the fluid kind.
Useful anchors for cooking: 100 g is 3.53 oz, 250 g is 8.82 oz, and a pound is 453.6 g. British recipes from before metrication often use 4 oz or 8 oz quantities, which are 113 g and 227 g.
