Use Cases

Cooking Unit Converter is useful in various culinary scenarios.

1. Converting International Recipes

International recipes often use cups, ounces, or pounds, but this tool easily converts them to grams and milliliters commonly used in Japan and other metric countries.

2. Adjusting Recipe Quantities

When doubling or halving recipes, accurately calculate each ingredient amount. Convert 1 cup to tablespoons or grams to milliliters for easier measuring.

3. Substituting Measuring Tools

Convenient for conversions when substituting available tools: how many teaspoons equal one tablespoon, or how many tablespoons equal one cup.

4. Precise Baking Measurements

Baking requires precise measurements. Even when a recipe says "1 cup", weight varies by ingredient. This tool helps confirm exact grams.

5. Diet & Nutrition Management

Nutrition labels use grams, but recipes often use volume units. This tool converts to accurate grams for nutrition calculations.

About Cooking Unit Conversion

Cooking unit conversion is the process of converting between commonly used culinary units: cups, tablespoons, teaspoons, grams, and milliliters.

Main Units

In Japanese cooking, 1 cup = 200ml, 1 tablespoon = 15ml, 1 teaspoon = 5ml are standards. In US measurements, 1 cup = 237ml. Converting between grams (weight) and milliliters (volume) depends on ingredient density.

Ingredient-Specific Density

Same volume has different weights by ingredient. For example: water is 1ml = 1g, but flour is 1ml ≈ 0.59g, sugar is 1ml ≈ 0.85g, salt is 1ml ≈ 1.20g. This tool provides accurate conversions considering ingredient-specific density.

Real-Time Conversion

All calculations happen instantly in your browser, so entering a value converts to all units immediately. No server communication means fast performance and privacy protection.

How many grams is 1 cup?

1 cup = 200ml (Japanese standard), but grams vary by ingredient. Water is 200g, flour is approximately 120g, sugar is approximately 170g, salt is approximately 240g, butter is approximately 180g.

How to convert tablespoons to teaspoons?

1 tablespoon = 3 teaspoons. Since 1 tablespoon = 15ml and 1 teaspoon = 5ml, it's a 3x relationship.

Difference from international cups?

Japanese 1 cup is 200ml, but US 1 cup ≈ 237ml (8 fluid ounces). This tool uses Japanese standard (1 cup = 200ml). Note: US recipes may require adjustment.

Do I need to select ingredient?

Converting between grams and milliliters requires ingredient density. Selecting an ingredient provides more accurate conversion results.

Can I use this offline?

Yes, all calculations happen in your browser, so once the page loads, it works offline.

Are calculation results accurate?

Ingredient densities use general values, but may vary slightly by origin, variety, and humidity. For more precise measurements, we recommend using a digital scale.

Can you add more ingredients?

We support major ingredients but are considering adding more. Please send feedback with your requests.

Can I use this commercially?

Yes, this tool is free for commercial use. Feel free to use it on recipe sites, blogs, etc.
