How many grams are in a tablespoon of flour?

One level 15 ml tablespoon is about 8 g of all-purpose flour. A heaped tablespoon weighs more and depends on how it is scooped.

How many grams are in 1 cup of flour?

In this converter, 1 US cup of all-purpose flour is about 130 g. Real values vary with flour type, humidity, sifting and packing.

Is a US cup 240 ml or 236.588 ml?

US.588 ml in this calculator. FDA labeling often rounds a cup to 240 ml, and metric cups are 250 ml.

What is a fluid ounce?

A fluid ounce, or fl oz, is a volume unit. A weight ounce, or oz, is a mass unit, so converting fl oz to grams requires an ingredient density.

Why do cooking measurement charts disagree?

Household measures depend on ingredient density, grind, humidity, sifting, packing and scooping style. For dry ingredients, a 10-20% spread is common.

Should I use cups or grams for baking?

Use grams and a kitchen scale for precise baking. Cups and spoons are helpful for quick cooking, but they are less repeatable for flour, cocoa, powdered sugar and starch.

How to use the cooking measurement converter

This converter translates common recipe measures: cups, tablespoons, teaspoons, milliliters, liters, fluid ounces and grams. Because cups and spoons measure volume, the gram result depends on ingredient density.

Choose an ingredient or enter a custom density in g/ml.
Enter the amount from the recipe.
Choose the source and target measure: grams, milliliters, spoons, cups or fluid ounces.
Use the result card to compare volume, weight and density.

Quick cooking measurement chart

Ingredient	1 US cup	1 level tablespoon	1 level teaspoon
Water	237 g	15 g	5 g
All-purpose flour	130 g	8 g	3 g
Granulated sugar	189 g	12 g	4 g
Table salt	284 g	18 g	6 g
Vegetable oil	218 g	14 g	5 g
Melted butter	215 g	14 g	5 g
Honey	336 g	21 g	7 g
White rice	177 g	11 g	4 g
Sour cream	251 g	16 g	5 g

Heaped spoon settings are practical estimates, not formal standards. The actual heap depends on ingredient texture and how the spoon is filled.

Why ingredient density matters

A spoon or cup gives volume, while grams measure mass. Flour is fluffy, honey is dense and oil is lighter than water, so the same cup can weigh very differently.

grams = milliliters \times ρ_{ingredient}

grams - ingredient weight; milliliters - selected measure volume; rho ingredient - average ingredient density in grams per milliliter.

milliliters = \frac{grams}{ρ _{ingredient}}

milliliters - volume used for spoon or cup conversion; grams - recipe weight; rho ingredient - average density for the selected ingredient.

Reverse conversion helps when a recipe gives grams but you only have measuring cups or spoons.

For bread, cakes, pastry creams and nutrition tracking, use a kitchen scale. Volume measures can vary enough to affect the result.

US cup, metric cup and fluid ounce

Measure	Volume	Where it appears
US cup	236.588 ml	Most US recipes and American measuring cups.
FDA cup	240 ml	Nutrition labeling and rounded household measures.
Metric cup	250 ml	Metric recipes, Australia, New Zealand and some Canadian sources.
US fluid ounce, fl oz	29.5735 ml	A volume unit, not a weight ounce.
200 ml glass	200 ml	Useful for converting older European or Eastern European glass measures.
250 ml glass	250 ml	Equivalent to a metric cup in this calculator.

Fluid ounces measure volume. Weight ounces measure mass. Do not treat fl oz and oz as the same unit in a recipe.

Accuracy limits

Ingredient densities are averages for home cooking, not laboratory measurements.
Flour, cocoa, powdered sugar and starch vary with grind, humidity, sifting and packing.
A heaped spoon is not standardized; a light heap and a large heap can differ a lot.
For precise baking, diet tracking and calorie calculations, verify the weight on a kitchen scale.

Dry ingredient volume can easily vary by 10-20%, so treat the output as a practical estimate.
