Cooking Measurement Converter

About the Cooking Measurement Converter

The all-in-one cooking measurement converter handles every common kitchen volume unit: cups, tablespoons, teaspoons, fluid ounces, and milliliters. Enter a value in any unit and see all equivalents together.

Recipe conversion is a frequent kitchen task. You might need to double a recipe, convert a European recipe from milliliters to cups, figure out how many teaspoons equal 30 mL, or determine how many tablespoons are in 3/4 cup. This single tool answers all of those questions.

All conversions use US customary standards (1 cup = 236.588 mL, 1 tbsp = 14.787 mL, 1 tsp = 4.929 mL). The relationships between units are clean: 1 cup = 16 tbsp = 48 tsp = 8 fl oz.

When This Page Helps

Instead of looking up individual conversions, enter any cooking volume amount and see all common units at once. Perfect for recipe scaling, ingredient substitution, and working with international recipes.

How to Use the Inputs

1. Select the unit you are starting with from the dropdown.
2. Enter the amount you want to convert.
3. All other cooking volume units appear as results.
4. Use this for recipe scaling by entering the scaled amount.
5. Check the quick reference for common kitchen equivalents.

Example Calculation

Tips & Best Practices

• Memorize the core ratio: 1 cup = 16 tbsp = 48 tsp = 8 fl oz.
• 1/4 cup = 4 tbsp = 12 tsp = 2 fl oz — a very common recipe amount.
• When halving recipes, 1 tbsp becomes 1.5 tsp (not a common measuring spoon — use 1 tsp + 1/2 tsp).
• For non-US recipes: 1 metric cup = 250 mL, 1 Australian tbsp = 20 mL.
• Use a liquid measuring cup (glass, with pour spout) for liquids and dry cups (flat rim) for dry ingredients.

The Kitchen Measurement System

US cooking measurements form a nested hierarchy: 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces. Within a cup: 16 tablespoons = 48 teaspoons. These clean ratios make mental math possible once you memorize the key relationships.

Common Recipe Scaling Math

When doubling a recipe, all measurements simply double. When halving, fractions get tricky. Half of 1/3 cup is 2 tbsp + 2 tsp. Half of 1 tbsp is 1.5 tsp. Knowing the tbsp/tsp relationship makes this easier.

International Recipe Conversion Tips

British recipes may use imperial cups (284 mL) or metric cups (250 mL). Australian recipes use 20 mL tablespoons. Japanese cups are 200 mL. Always check the recipe source to determine which standard applies before converting.

Frequently Asked Questions

• How many tablespoons in a cup?

  There are exactly 16 US tablespoons in 1 US cup. This means 1/4 cup = 4 tbsp, 1/3 cup ≈ 5.33 tbsp, 1/2 cup = 8 tbsp, and 3/4 cup = 12 tbsp.

• How many teaspoons in a tablespoon?

  There are exactly 3 US teaspoons in 1 US tablespoon. So 1 tablespoon = 3 teaspoons, 2 tablespoons = 6 teaspoons, etc.

• How do I convert fluid ounces to cups?

  Divide the number of fluid ounces by 8. One US cup = 8 US fluid ounces. So 4 fl oz = 1/2 cup, 6 fl oz = 3/4 cup, 12 fl oz = 1.5 cups.

• What is the difference between dry and liquid measuring cups?

  Both hold the same volume (1 cup = 236.588 mL). Liquid cups have a pour spout and extra space above the line. Dry cups have a flat rim for leveling. Using the right type improves measurement accuracy.

• How do I measure 2/3 cup without a 2/3 cup measure?

  Use 10 tablespoons + 2 teaspoons (10.667 tbsp total). Alternatively, fill a 1/3 cup measure twice, or use a liquid measuring cup with mL markings and measure 158 mL.

• Are cooking measurements standardized internationally?

  No. The US, UK, Australia, and metric-using countries each have slightly different definitions for cups, tablespoons, and teaspoons. US cup = 236.6 mL, metric cup = 250 mL, Australian tbsp = 20 mL vs US tbsp = 14.8 mL.
