About this calculator
A cooking measurement converter changes an ingredient amount between volume measures (cups, tablespoons, teaspoons, milliliters, fluid ounces) and weight measures (grams, ounces, pounds). Because a cup of flour and a cup of honey weigh very different amounts, it uses the density of the ingredient you pick to cross between volume and weight.
When both units are volumes, or both are weights, it is a straight conversion; the density only comes into play when you cross between the two. Densities range widely — all-purpose flour is about 0.53 g/ml while honey is about 1.42 g/ml — which is why the same cup can weigh anywhere from roughly 125 g to 336 g depending on what fills it.
Worked example: one US cup (236.6 ml) of all-purpose flour at 0.53 g/ml weighs about 125 grams, whereas a cup of granulated sugar at 0.85 g/ml weighs about 200 grams. A results table shows the amount in every cooking unit at once, so you can follow a metric recipe with US measuring cups or the reverse.
Frequently asked questions
How many grams are in a cup of flour?
About 125 grams for all-purpose flour, because flour is light (roughly 0.53 g per ml). A cup of granulated sugar is heavier, around 200 grams.
Why do I need to pick an ingredient?
Cups and tablespoons measure volume, while grams and ounces measure weight. Converting between them needs the ingredient density — a cup of honey weighs far more than a cup of flour.
Are these US or metric cups?
This uses the US customary cup of about 236.6 ml. A metric cup is 250 ml and an Australian tablespoon is larger, so results are approximate for those systems.
How many grams are in a cup of sugar?
Granulated sugar has a density of about 0.85 g/ml, so a US cup (236.6 ml) weighs roughly 200 grams. Brown sugar packed into the cup is a little heavier, about 220 grams.
Why does a cup of honey weigh more than a cup of flour?
Honey is far denser — about 1.42 g/ml versus flour’s 0.53 g/ml — so the same cup holds much more mass. This cooking measurement converter stores a density for each ingredient to handle exactly this.
How many tablespoons are in a cup?
A US cup contains 16 tablespoons, and each tablespoon is 3 teaspoons, so a cup is 48 teaspoons. These volume relationships hold whatever the ingredient.
