Why does the same cup give different gram weights for different ingredients?

Weight depends on density. A cup of flour is light and fluffy at roughly 125 g, while a cup of honey is dense at about 340 g. Selecting the right ingredient applies the correct density for an accurate weight.

Are the cups US or metric?

The cup here is the US customary cup of 236.59 ml. A metric cup is 250 ml, so if your recipe is European, expect a small difference of about 5 percent.

How many teaspoons are in a tablespoon?

There are 3 teaspoons in a US tablespoon, and 16 tablespoons in a US cup. The converter handles all of these splits automatically when you choose the units.

Can I rely on volume-to-gram conversions for baking?

They are accurate for liquids and good for dry goods, but flour especially varies with how it is scooped or sifted. For precision baking, weighing on a scale is always the most reliable method.

The Cooking Measurement Converter handles the two conversions home bakers reach for most: swapping between volume units like cups, tablespoons, teaspoons, fluid ounces and millilitres, and turning a volume into a weight in grams. Because a cup of flour and a cup of honey weigh very different amounts, the grams output uses ingredient-specific densities rather than a single fudge factor, so the numbers match trusted baking references.

How it works

Type the amount, pick the unit you are converting from, and pick the volume unit you want the answer in — for example one cup to tablespoons.
For weight, the calculator multiplies your volume by the chosen ingredient’s density (grams per millilitre) so the same one-cup volume gives 125 g of flour but about 340 g of honey.
All US customary kitchen units are supported (teaspoon, tablespoon, fluid ounce, cup, pint, quart) alongside metric millilitres and litres.

Worked example

A recipe lists 1 cup of all-purpose flour but your scale works in grams.

1 cup = 236.588 ml of volume.
All-purpose flour density ≈ 0.5284 g/ml.
Weight = 236.588 × 0.5284 ≈ 125 g.

1 cup of all-purpose flour weighs about 125 g, and equals 16 tablespoons by volume.
