About the Cooking Unit Converter

The Cooking Unit Converter is a free online tool that lets you convert between common cooking and baking measurements instantly. Whether you need to convert cups to grams, tablespoons to milliliters, or ounces to liters, this tool handles it all — including ingredient-specific density conversions for accurate weight-to-volume results.

Why Ingredient-Specific Conversions Matter

Many online converters only handle simple volume-to-volume or weight-to-weight conversions. But in real cooking and baking, you often need to convert between weight and volume (e.g., "how many grams is 1 cup of flour?"). The answer depends on the ingredient because different ingredients have different densities:

As you can see, 1 cup of honey weighs nearly 3 times as much as 1 cup of cocoa powder. Using a generic "1 cup = 240 g" conversion would give wildly inaccurate results for most dry ingredients.

Supported Units

The converter supports these common cooking measurements:

Volume Units

• Cup (US) — 236.588 ml. The standard US measuring cup.
• Tablespoon (tbsp) — 14.787 ml. There are 16 tablespoons in a cup.
• Teaspoon (tsp) — 4.929 ml. There are 3 teaspoons in a tablespoon.
• Milliliter (ml) — The metric base unit for small liquid volumes.
• Liter (L) — 1,000 ml. Common in metric recipes.
• Fluid Ounce (fl oz) — 29.574 ml. There are 8 fluid ounces in a cup.

Weight Units

• Gram (g) — The metric base unit for weight. Most precise for baking.
• Ounce (oz) — 28.35 grams. Used in US recipes for weight.
• Pound (lb) — 453.6 grams or 16 ounces.
• Kilogram (kg) — 1,000 grams. Used for larger quantities.

How to Use the Cooking Unit Converter

1. Enter an amount — Type the quantity you want to convert (e.g., "2" for 2 cups). Decimals and fractions are accepted.
2. Select your units — Choose the "From" and "To" units using the dropdown menus.
3. Select an ingredient (if needed) — When converting between weight and volume (e.g., cups to grams), an ingredient selector will appear. Pick your ingredient for an accurate density-based conversion.
4. View instant results — The result updates in real time as you type. A visual measuring cup animation and quick reference table show the conversion at a glance.
5. Swap or copy — Use the swap button (⇄) to reverse the conversion, or copy the result with one click.

Frequently Asked Questions (FAQ)

How many grams are in a cup?

It depends on the ingredient. One cup of all-purpose flour weighs about 120 grams, one cup of granulated sugar weighs about 200 grams, and one cup of butter weighs about 227 grams. This is why ingredient-specific conversions are important for baking accuracy.

How many tablespoons are in a cup?

There are 16 tablespoons in one US cup. This is a standard volume-to-volume conversion that applies regardless of the ingredient being measured.

What is the difference between fluid ounces and ounces?

Fluid ounces (fl oz) measure volume while ounces (oz) measure weight. One fluid ounce of water weighs approximately one ounce, but this relationship does not hold for other ingredients. For example, one fluid ounce of honey weighs about 1.5 ounces because honey is denser than water.

Why do I need to select an ingredient for some conversions?

When converting between weight units (grams, ounces) and volume units (cups, tablespoons, milliliters), the ingredient matters because different ingredients have different densities. A cup of flour is much lighter than a cup of honey. Selecting the ingredient ensures the conversion uses the correct density for accurate results.

How many teaspoons are in a tablespoon?

There are 3 teaspoons in one tablespoon. This is a universal measurement standard used in cooking across the United States and many other countries.

Tips for Accurate Measuring

• Weigh dry ingredients — For baking precision, use a kitchen scale and measure in grams. Volume measurements for flour can vary by 20% or more depending on how tightly packed the cup is.
• Use the spoon-and-level method — When measuring flour by volume, spoon flour into the cup and level off with a straight edge. Do not scoop directly from the bag, which compacts the flour.
• Liquid at eye level — When measuring liquids, place the measuring cup on a flat surface and read at eye level to ensure accuracy.
• Temperature matters — Butter and coconut oil densities assume room temperature (melted for coconut oil). Chilled butter is denser when packed into a cup.
