Cooking Measurement Converter

Convert between cups, tablespoons, teaspoons, milliliters, fluid ounces, and grams for common ingredients.

Measurement system
Equivalents

Weight in grams is approximate because ingredient densities vary. Everything runs in your browser.

How to convert cooking measurements

  1. Enter an amount

    Type the quantity from your recipe and pick the unit you are starting from.

  2. Pick a system and ingredient

    Choose US or metric cup sizes and select the ingredient so grams are estimated correctly.

  3. Read the equivalents

    Every kitchen unit, including grams for the chosen ingredient, updates instantly.

  4. Copy a value

    Copy a single result or the whole list to paste into your notes or recipe.

Why use this tool

Volume and weight together

Cups, tablespoons, teaspoons, milliliters, liters, and fluid ounces sit next to a grams estimate for the ingredient you select.

Ingredient aware grams

Flour, sugar, butter, honey, and other staples each use their own density so a cup of flour and a cup of honey do not weigh the same.

US and metric cups

A single toggle switches cup, tablespoon, and teaspoon sizes between US customary and metric so the numbers match your recipe.

Live results

Every equivalent recalculates as you type. There is no convert button and no page reload.

Private by design

All conversion runs on your device. Your recipe never leaves the page. No upload, no signup.

About this tool

Recipes rarely agree on units. One calls for cups, another for grams, and a third for tablespoons, and jumping between them mid-cook is where mistakes happen. This converter puts kitchen volume units and a grams estimate side by side so you can move a single amount across all of them at once.

Volume to weight is the hard part because it depends on what you are measuring. A cup of flour weighs far less than a cup of honey, so grams here are calculated from an approximate density for the ingredient you choose. Densities vary with how packed or sifted something is, so treat grams as a close estimate rather than a lab figure. For volume-only conversions the results are exact.

Cups are not standardised worldwide either, so the system toggle switches cup, tablespoon, and teaspoon sizes between US customary and metric. Milliliters and liters stay constant and act as the shared base for everything. For scaling a whole recipe up or down, pair this with the recipe scaler, and for general liquid measures see the volume converter.

Frequently asked questions

How many grams are in a cup?
It depends on the ingredient. A US cup of all-purpose flour is about 125 grams, a cup of granulated sugar is about 200 grams, and a cup of water is about 237 grams. Pick the ingredient to get the right estimate.
Why are grams only an estimate?
Weight per volume changes with how packed, sifted, or settled an ingredient is. The tool uses a representative density for each ingredient, which gets you close but is not a precise laboratory measurement.
What is the difference between US and metric cups?
A US customary cup is about 237 milliliters while a metric cup is 250 milliliters. Tablespoons and teaspoons differ too, so use the system toggle to match your recipe.
Can I convert from grams back to cups?
Yes. Choose grams as the from unit, set the ingredient, and the tool works backward to cups, tablespoons, and the other volume units.
Is my data sent anywhere?
No. Every calculation happens on your device as you type. Nothing is uploaded and no account is needed.
