1 cup = 16 tbsp = 240 ml · 1 tbsp = 3 tsp = 15 ml · 1 tsp = 5 ml · 1 stick butter = 113 g
Volume-to-weight depends on the ingredient (a cup of flour ≈ 120 g but a cup of water = 240 g), so weigh for baking accuracy. Note the US cup is 240 ml while the metric cup is 250 ml and the UK imperial cup is ~284 ml.
Convert recipes with confidence
Recipes mix volume (cups, spoons) and weight (grams, ounces), and the relationship between them depends on the ingredient's density. Choose your ingredient so the calculator uses the right density — then enter any amount in any unit and read all the others at once.
For baking especially, weighing in grams gives the most consistent results.
