Kitchen Measurement Converter

Convert common cooking and baking measurements between US and metric units with the Kitchen Measurement Converter. Change cups to grams, grams to cups, ounces to grams, millilitres to cups and more — with ingredient-specific conversions when weight and volume are involved.

Use it for everyday cooking, baking, international recipes and those moments when a recipe gives you exactly the measurement system you don’t have handy.

How the Kitchen Measurement Converter Works

Enter the amount you want to convert, choose the From and To units, and select an ingredient when the conversion involves both volume and weight.

The Kitchen Measurement Converter can handle standard measurement conversions directly. For ingredient-specific conversions such as cups to grams or grams to cups, it uses the selected ingredient because a cup of flour does not weigh the same as a cup of sugar, butter or honey.

Common Kitchen Measurement Conversions

Some kitchen measurements convert directly because they measure the same thing. Others need the specific ingredient because volume and weight are not interchangeable.

For standard volume conversions:

• 1 US cup = 16 tablespoons
• 1 US cup = about 237 mL
• 1 tablespoon = 3 teaspoons
• 1 US tablespoon = about 14.8 mL
• 1 teaspoon = about 4.9 mL
• 1 litre = 1,000 mL

For weight conversions:

• 1 ounce = about 28.35 g
• 1 pound = 16 ounces
• 1 pound = about 454 g
• 1 kilogram = 1,000 g

The important exception is volume-to-weight conversion. One cup of flour, sugar, butter and honey all have different weights, so the Kitchen Measurement Converter asks for the ingredient when that information is needed.

Why Cups and Grams Are Not a Direct Conversion

Cups measure volume, while grams measure weight. That means there is no single cups-to-grams formula that works for every ingredient.

For example:

• 1 US cup of all-purpose flour weighs about 120 g
• 1 US cup of granulated sugar weighs about 198 g
• 1 US cup of butter weighs about 227 g
• 1 US cup of honey weighs about 340 g

That is why the Kitchen Measurement Converter asks you to choose an ingredient when converting between volume and weight.

The exact weight can still vary slightly depending on the brand, how tightly the ingredient is packed and how it is measured, so ingredient conversions should be treated as practical kitchen estimates rather than laboratory measurements.

US Cups, Metric Cups and Australian Tablespoons

Not every recipe uses the same cup and tablespoon size, especially when recipes come from different countries.

A US cup is about 236.6 mL, while a metric cup is 250 mL. That difference is small, but it can matter in baking when several cups of an ingredient are involved.

Tablespoons can differ too:

• 1 US tablespoon = about 14.8 mL
• 1 Australian tablespoon = 20 mL
• 1 teaspoon = about 4.9 mL

The Kitchen Measurement Converter includes both US and metric cup options, plus Australian tablespoons, so you can match the measurement system used by the recipe instead of assuming every cup or tablespoon is identical.

Fahrenheit and Celsius Cooking Temperature Conversion

The Kitchen Measurement Converter also converts cooking temperatures between Fahrenheit and Celsius, which is useful when a recipe uses a different oven scale from the one you normally cook with.

Common oven temperatures include:

• 300°F ≈ 149°C
• 325°F ≈ 163°C
• 350°F ≈ 177°C
• 375°F ≈ 191°C
• 400°F ≈ 204°C
• 425°F ≈ 218°C
• 450°F ≈ 232°C

Ovens do not always let you choose an exact converted temperature, so use the nearest practical setting your oven allows.

Frequently Asked Questions

Can I convert cups to grams?

Yes, but you need to select the ingredient. Cups measure volume and grams measure weight, so the result depends on what you are measuring.

For example, 1 cup of flour does not weigh the same as 1 cup of sugar or honey.

Can I convert grams back to cups?

Yes. The Kitchen Measurement Converter works in both directions. Select the ingredient, enter the gram amount, and choose the cup measurement you want.

Does the converter support metric measurements?

Yes. It includes grams, kilograms, millilitres, litres and metric cups, as well as common US kitchen measurements.

What is the difference between a US cup and a metric cup?

A US cup is about 236.6 mL, while a metric cup is 250 mL.

Why do ingredient conversions say they are approximate?

Ingredient weight can change depending on brand, moisture, packing and measuring method. The converter uses practical reference values, but small differences are normal.

Can I convert oven temperatures too?

Yes. Choose Temperature at the top of the converter to switch between Fahrenheit and Celsius.

What does “Kitchen-Friendly Result” mean?

The converter tries to show measurements in a form that is easier to use in a real kitchen. Where appropriate, that can mean familiar fractions such as ½ cup or ¾ cup instead of awkward decimal measurements.
