Converting by hand works. Weighing skips the conversion, and the error that comes with it, entirely. Quantities come straight from your calculation above — check them against your supplier's pack sizes before ordering.
Tools & equipment
Digital kitchen scale
Weighing removes the cup-packing variable entirely, which is the single biggest accuracy win in baking.
Dry measuring cups
Straight-rimmed, so you can sweep the excess off level with a knife.
Measuring spoons
For the awkward amounts a scaled recipe lands on.
Liquid measuring cup
Read it at eye level on a flat surface, not held up in the air.

How to use the cooking measurement converter
A cup measures volume and a gram measures weight, so there is no single answer to how many grams are in a cup — it depends entirely on what you are measuring. A cup of flour is about 120 g; a cup of honey is about 340 g. Pick your ingredient, enter what the recipe says, and every equivalent is shown at once.
Why one cup is not one weight
Volume measures how much space something takes up. Weight measures how much of it there is. The bridge between them is density, and density is a property of the specific ingredient — which is why this page asks what you are measuring before it answers.
The spread is larger than most people expect. A cup of cocoa powder weighs about 85 g. A cup of honey weighs about 340 g — four times as much for the same space. Any converter that offers you a single cups-to-grams number without asking what is in the cup is guessing.
Measuring flour accurately without a scale
If you are working from cups, how you fill the cup matters more than which cup you own. Stir the flour in the bag or canister to loosen it, spoon it lightly into the measuring cup until it mounds over the rim, then sweep the excess off level with a straight edge. That is the method the 120 g figure assumes.
Dipping the cup into the bag packs the flour down and typically gives you 140 to 150 g instead. Over a batch of bread that is most of an extra half cup, and it is the single most common reason a recipe comes out dry.
What this calculator assumes
Every estimate depends on figures that vary by supplier and conditions. These are the ones used here, so you can sanity-check the result against your own quote.
- Cups are US customary cups of 236.588 ml — the cup American recipes are written in, not the 240 ml legal cup used on nutrition labels.
- Ingredient weights follow King Arthur Baking published cup weights. They assume flour is spooned into the cup and levelled off; scooping straight from the bag compacts it and can add 20% or more.
- Cup weights are averages. Humidity, how finely something is ground, how firmly it is packed and brand differences all move the real number by a few percent.
- Kosher salt is listed by brand because the difference is not small: a cup of Diamond Crystal weighs about 134 g and the same cup of Morton weighs about 230 g. Substituting one for the other by volume will noticeably change how food tastes.
- Ounces here are weight ounces except where a row explicitly says fluid ounces. They are not interchangeable.
Frequently asked questions
How many grams are in a cup?
It depends on the ingredient, because a cup measures volume rather than weight. A cup of all-purpose flour is about 120 g, granulated sugar about 200 g, butter 227 g, and honey about 340 g. Water is about 237 g. There is no single conversion that works for everything.
Why do baking recipes give weights instead of cups?
Because weight is reproducible and volume is not. Two people measuring a cup of flour can differ by 20% or more depending on whether they scoop or spoon it, and that difference is the gap between a tender crumb and a dry, tough one. A digital scale removes the variable entirely, which is why most serious baking references now lead with grams.
Is a US cup the same as a metric cup?
No. A US customary cup is 236.588 ml, an Australian metric cup is 250 ml, and the legal cup used on US nutrition labels is 240 ml. This converter uses the 236.588 ml US customary cup, which is what American recipes mean. The difference is around 5%, which matters for baking and rarely matters for soup.
How many tablespoons are in a cup?
Sixteen tablespoons in a US cup, and three teaspoons in a tablespoon, so 48 teaspoons to the cup. Those ratios are fixed and hold for any ingredient, because they are all volume measures.
