How many grams in a 12 oz bag of coffee?
A 12 oz bag of coffee contains 340 grams. At a standard dose of 15 g per cup, that yields approximately 22–23 cups. At a lighter 10 g dose, you get closer to 34 cups.
How many ounces is a tablespoon of coffee?
One tablespoon of ground coffee weighs approximately 0.21 oz (coarse) to 0.32 oz (fine). At medium grind, 1 tablespoon ≈ 0.26 oz (7.5 g).
Why do coffee bags use ounces in the US but grams elsewhere?
The US uses the imperial system, so retail packaging shows ounces. Specialty coffee roasters worldwide use grams for brew recipes because they're more precise. A 12 oz US bag and a 340 g international bag contain the same amount of coffee.
