Baking Conversion Calculator

Convert cups, grams, tablespoons, teaspoons, and ounces for baking. Choose the ingredient first—flour, sugar, and butter do not weigh the same per cup.

What is a baking conversion calculator?

US recipes often list cups and spoons. Kitchen scales and metric recipes use grams. Those systems only match after you know what is in the cup.

This tool converts:

A cup measures space. A gram measures mass. Packed brown sugar fills that space with more mass than sifted cocoa. There is no universal 1 cup = X grams number for baking.

Examples from this calculator:

  • Volume: US cups, tablespoons, teaspoons, fluid ounces, milliliters
  • Weight: grams, kilograms, ounces, pounds
  • Weight and volume for common baking ingredients, each with its own US cup weight
  • 1 cup all-purpose flour → approximately 120 g (spoon-and-level)
  • 1 cup granulated sugar → approximately 200 g
  • ½ cup butter (1 US stick) → approximately 113.5 g
  • 100 g flour → approximately 0.83 cup
  • 2 tablespoons butter → approximately 28.4 g

Always select the ingredient for cups ↔ grams. Flour, sugar, and butter do not share one conversion factor.

Flour assumes spoon-and-level. Brown sugar assumes packed. Butter: ½ cup = 1 US stick. 100 g column is grams → cups.

Volume equivalents (any ingredient)

These do not depend on density. Use them when a recipe mixes cups and spoons.

How to use the baking conversion calculator

  1. Choose an ingredient

    Select flour, sugar, butter, or another listed ingredient. This matters whenever you convert between a volume unit and a weight unit.

  2. Enter the amount

    Type a decimal or a fraction, such as 1, 0.5, 1/2, or 1 1/2.

  3. Select the starting unit

    Choose the unit in the recipe: cups, tablespoons, teaspoons, fluid ounces, milliliters, grams, ounces, kilograms, or pounds.

  4. Select the target unit

    Choose what you want to measure with. Use Swap to reverse the conversion.

  5. Read or copy the result

    The converted amount appears immediately. Copy it, share the link, or tap a common-amount shortcut for the same ingredient.

How the conversions work

The calculator uses three kinds of math. Volume-to-volume and weight-to-weight are exact unit conversions. Weight-to-volume uses each ingredient’s grams per US cup.

Formula

Volume → volume: target = amount × (ml per from-unit) ÷ (ml per to-unit)
Weight → weight: target = amount × (g per from-unit) ÷ (g per to-unit)
Volume → weight: grams = cups × grams-per-cup for that ingredient
Weight → volume: cups = grams ÷ grams-per-cup

Assumptions

  • US customary cup = 8 fluid ounces = 236.59 ml
  • 16 tablespoons = 1 cup; 3 teaspoons = 1 tablespoon
  • All-purpose flour: spoon-and-level ≈ 120 g/cup
  • Granulated sugar ≈ 200 g/cup; packed brown sugar ≈ 220 g/cup; unsifted powdered sugar ≈ 113 g/cup
  • Butter ≈ 227 g/cup (US stick butter convention)
  • Cocoa ≈ 85 g/cup; rolled oats ≈ 90 g/cup; honey ≈ 336 g/cup; vegetable oil ≈ 198 g/cup
  • Milk ≈ 240 g/cup; water ≈ 237 g/cup
  • Baking powder ≈ 4 g/teaspoon; baking soda ≈ 6 g/teaspoon

Limitations

  • Scoop-and-sweep flour can weigh much more than 120 g per cup
  • Brand, humidity, and packing change real cup weights
  • These are kitchen standards, not laboratory densities
  • Flour here is all-purpose only — bread flour and cake flour differ
  • Rice water ratios belong on the Rice Ratio Calculator, not this page

Baking Conversion Calculator examples

1 cup flour to grams

Input

1 cup all-purpose flour

Output

approximately 120 g

Spoon-and-level US cup weight used by this calculator.

1 cup sugar to grams

Input

1 cup granulated sugar

Output

approximately 200 g

Granulated sugar is denser than flour, so the same cup weighs more.

½ cup butter to grams

Input

1/2 cup butter (1 US stick)

Output

approximately 113.5 g

1 cup butter = 227 g, so one stick is half of that.

100 grams flour to cups

Input

100 g all-purpose flour

Output

approximately 0.83 cup

100 ÷ 120 = 0.833…, shown as 0.83 cup.

2 tablespoons butter to grams

Input

2 tbsp butter

Output

approximately 28.4 g

2 ÷ 16 × 227 = 28.375 g, rounded for the kitchen.

Common mistakes to avoid

Assuming every ingredient uses the same cups-to-grams number

Select flour, sugar, butter, or another listed ingredient. Density changes the result.

Treating grams and milliliters as interchangeable

That only holds for water. Oil, honey, and flour do not weigh 1 g per ml.

Packing flour into the measuring cup

Spoon flour in and level it, or weigh 120 g per cup on a scale.

Using a flour conversion for honey, cocoa, or brown sugar

Dense or packed ingredients need their own cup weight. Honey is 336 g per cup here.

Confusing fluid ounces with weight ounces

Choose “Fluid ounces” for volume and “Ounces (weight)” for mass.

Using volume when the recipe already specifies weight

If the formula is in grams, weigh it. Convert only when you must translate units.

Frequently asked questions

How many grams are in a cup of flour?

About 120 g for 1 US cup of all-purpose flour using the spoon-and-level method in this calculator. Scooping from the bag packs extra flour and raises the weight.

How many grams are in a cup of sugar?

200 g for 1 US cup of granulated sugar. Packed brown sugar is about 220 g per cup here; unsifted powdered sugar is about 113 g.

Is 1 cup always the same weight?

No. A cup is a volume. Flour, sugar, butter, honey, and cocoa each fill that volume with a different mass. That is why this tool asks for the ingredient.

How many tablespoons are in a cup?

16 US tablespoons equal 1 US cup. That conversion is the same for every ingredient because both units measure volume.

How many teaspoons are in a tablespoon?

3 US teaspoons equal 1 tablespoon. There are 48 teaspoons in 1 cup.

Are grams more accurate than cups for baking?

Usually yes. A scale repeats more reliably than a scooped cup, especially for flour. Use this converter to translate a cup recipe, then weigh when the bake is sensitive.

How do I convert butter from cups to grams?

Select butter, enter the cups (or 1/2 for a US stick), and set the target to grams. 1 cup is 227 g; ½ cup is 113.5 g.

What is the difference between fluid ounces and ounces?

Fluid ounces measure volume (like cups and milliliters). Ounces here are weight (like grams). 8 fluid ounces of water is about 1 cup, but 8 ounces by weight of flour is a different amount.

Can I convert any ingredient from cups to grams?

Only the ingredients listed in the calculator. Each one has a published US cup weight. An unlisted item—such as bread flour or a mix—needs its own density.

Should I use this page or the recipe scaler?

Use this page to change units (cups to grams, tablespoons to grams). Use the Recipe Scaler when you already have the amounts and need more or fewer servings.

What to do next

Continue the workflow with the right follow-up tool.

When this tool isn't the right choice

You need bread flour, cake flour, or another flour type

The flour option is all-purpose only (120 g/cup). Other flours do not match.

You only need to change serving counts

Use the Recipe Scaler, then convert units here if the scaled recipe mixes cups and grams.

You need oven temperature or gas mark conversion

Use the Oven Temperature Converter.

You need rice-to-water cooking ratios

Use the Rice Ratio Calculator. This page does not own rice cooking hydration.

Privacy, accuracy, and trust

Privacy

Amounts and ingredient choices are processed in your browser—nothing is uploaded to EverydayTools servers for the core conversion.

Accuracy

Conversions use fixed US baking densities (flour 120, sugar 200, brown sugar 220, butter 227 g per cup, and the other listed cup weights). Real kitchens vary with packing and humidity.

How this tool works

Math runs client-side after you enter amount, units, and ingredient.

Educational kitchen converter. Cup weights are practical averages—not lab density measurements. Prefer a digital scale for precision baking.
