Coffee (brewed): Grams to Cups
1 cup of coffee (brewed) = 237 grams
One US cup of coffee (brewed) weighs 237 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 250 grams. To convert any weight, divide the grams by the figure for your cup.
A cup (8 fl oz) of brewed coffee weighs 237 g (USDA FoodData Central, coffee brewed with tap water), the same as a cup of water because brewed coffee is almost all water. A 6 fl oz serving is 178 g and each fluid ounce is 29.6 g. Instant coffee powder is very light by comparison: USDA weighs a teaspoon at about 1 g and a single-serve packet at 2 g.
