How do I convert cooking measurements like cups to grams, tablespoons or millilitres?

Type a value into AnyTool Cooking Unit Converter and pick the units. It converts volume to volume (cups, tablespoons, teaspoons, fluid ounces, millilitres, litres, pints, quarts, gallons and the 250 mL metric cup) and weight to weight (grams, kilograms, ounces, pounds) directly. For cups to grams it uses the selected ingredient — a cup of flour weighs about 120 g, a cup of sugar about 198 g and a cup of honey about 340 g — because volume and weight only relate through that ingredient’s density. Everything runs in your browser, so nothing is uploaded.

What is

Cooking Measurement Conversion

Cooking measurement conversion changes a recipe quantity from one unit to another — for example cups to grams or tablespoons to millilitres. Volume-to-volume and weight-to-weight conversions are fixed, but converting volume to weight (such as cups to grams) depends on the ingredient’s density, because a cup of flour and a cup of honey weigh very different amounts. King Arthur Baking lists one cup of all-purpose flour as about 120 grams and one cup of granulated sugar as about 198 grams.

Frequently Asked Questions

One cup of all-purpose flour weighs roughly 120 grams according to the King Arthur Baking ingredient weight chart, though it can range from about 110 to 145 grams depending on whether the flour is scooped, spooned or sifted. The Cooking Unit Converter uses 120 g per cup for flour and lets you switch ingredients, since a cup of sugar (~198 g) or honey (~340 g) weighs much more.

About 120 grams for all-purpose flour, per the King Arthur Baking chart — but it varies with scooping and sifting.

A cup measures volume and a gram measures weight, so the two only connect through the ingredient’s density (grams per millilitre). A cup of flour weighs about 120 grams, a cup of granulated sugar about 198 grams and a cup of honey about 340 grams — all the same volume but very different weights. That is why the Cooking Unit Converter asks you to choose an ingredient before it converts between cups and grams.

Because volume and weight only relate through density, and every ingredient has a different density.

One US cup equals 16 US tablespoons, which is 48 US teaspoons or 8 US fluid ounces (about 236.6 millilitres). One US tablespoon is 3 teaspoons or half a fluid ounce (about 14.79 mL). These volume-to-volume conversions are exact and do not depend on the ingredient, so the Cooking Unit Converter handles them without a density.

AnyTool Cooking Unit Converter computes every result locally in JavaScript using exact volume and weight factors through millilitre and gram bases, plus cited ingredient densities for cups-to-grams. No value is uploaded, there is no tracking, and the page keeps working offline after the first load.

No. Every conversion runs in your browser, so nothing is sent to a server and it works offline.

Detailed Explanation

Methodology

How the Cooking Unit Converter Works

AnyTool Cooking Unit Converter performs every calculation in the browser using two physical bases — millilitres for volume and grams for weight. Volume units (cups, tablespoons, teaspoons, fluid ounces, millilitres, litres, pints, quarts, gallons and the 250 mL metric cup) each carry an exact factor to millilitres, and weight units (grams, kilograms, ounces, pounds) carry an exact factor to grams, so volume↔volume and weight↔weight conversions are pure and ingredient-free. To cross between the bases — converting cups to grams, for example — the converter multiplies by the selected ingredient’s density in grams per millilitre, derived from published grams-per-cup figures (one US cup is 236.5882365 mL).

Ten volume units and four weight units in one model
Millilitre and gram bases; each unit is one exact factor
Volume↔weight uses ingredient density (grams per millilitre)
Editing the value updates the result live; swap reverses the units
All arithmetic is client-side JavaScript — no server round-trip

How It Works

Ingredient Densities and Why They Matter

A cup measures volume and a gram measures weight, so the two only relate through an ingredient’s density. The converter ships real, cited grams-per-cup figures — primarily from the King Arthur Baking ingredient weight chart, supplemented by The Calculator Site and allrecipes for kitchen staples. All-purpose flour is about 120 g per cup, bread flour 120 g, granulated sugar 198 g, packed brown sugar 213 g, powdered sugar 113 g, butter 227 g, water 237 g, milk 242 g, honey 340 g, cocoa powder 85 g, rolled oats 90 g, uncooked rice 185 g, table salt 273 g and olive oil 216 g. Because real weight shifts with scooping, sifting and packing, the converter labels these as approximate and recommends a kitchen scale for baking precision.

All-purpose flour ≈ 120 g per cup (King Arthur Baking)
Granulated sugar ≈ 198 g, butter ≈ 227 g, honey ≈ 340 g per cup
Densities convert grams-per-cup to grams-per-millilitre via 236.5882365 mL
Over 20 ingredients, each carrying its cited source
A per-ingredient table shows 1 cup, 1/2 cup, 1 tbsp and 1 tsp weights

Privacy & Security

Privacy and Offline Use

Because all conversion runs in the browser, no value is sent to a server, there is no account or tracking, and the page works offline after first load. The volume and weight factors come from the same shared, unit-tested conversion engine that other AnyTool converters reuse, and the cooking-specific density logic lives in a small pure module, so results are consistent and verifiable.
