🍳 Cooking Converter
Convert between cups, tablespoons, teaspoons, milliliters and grams for cooking.
Whether you are following a family recipe passed down in cups or trying out a European blog that lists ingredients in grams, converting cooking measurements can be the trickiest part of any meal prep. This cooking converter handles all the common kitchen units — cups, tablespoons, teaspoons, milliliters, grams, and ounces — so you can focus on getting dinner on the table instead of doing mental math.
Imagine you find a gorgeous Italian pasta recipe that calls for 250 mL of cream, but your measuring cups only show cups and tablespoons. No problem: enter 250, select “Milliliter” as the source and “Cup” as the target, and you will instantly see the equivalent. Or perhaps you are scaling down a batch of cookies from 24 to 12 and need to halve that ⅔ cup of sugar — the converter works with any value, so scaling is as simple as typing in the new amount.
For water-based liquids, grams and milliliters are interchangeable (1 g of water = 1 mL), which makes this converter especially handy when a recipe calls for 200 g of milk but you only have a milliliter jug. The tool uses smart precision formatting too: tiny amounts show more decimal places, while larger quantities stay clean and readable.
Whether you are baking, meal-prepping, or just trying a new cuisine, this converter is your go-to kitchen sidekick. Bookmark it and say goodbye to the days of Googling “how many tablespoons in a cup” mid-recipe.
How the conversion works
Every volume unit in this tool is expressed in milliliters, its base unit. The converter stores one fixed factor per unit: 1 cup = 240 mL, 1 tablespoon = 15 mL, 1 teaspoon = 5 mL, 1 ounce = 28.35 mL, and 1 gram = 1 mL. To convert between any two units it uses a single, consistent path:
- Convert your amount into milliliters. Multiply your amount by the “from” unit’s factor. So 2 cups × 240 = 480 mL.
- Convert those milliliters into the target unit. Divide by the “to” unit’s factor. So 480 mL ÷ 15 = 32 tablespoons.
For grams and ounces, the tool assumes the density of water (1 g ≈ 1 mL), which is accurate for liquids like water, milk, and broth. This means grams and milliliters are treated as interchangeable for volume purposes.
Worked example: A recipe calls for 250 mL of cream, but you measure in cups. 250 ÷ 240 = 1.042 cups, or just over one cup. You could use a full cup and a splash.
Worked example: You need ⅔ cup of sugar and want tablespoons. ⅔ × 240 = 160 mL, then 160 ÷ 15 = 10.67 tablespoons — about 10½ tablespoons.
Practical examples with real data
The table below is worked out by hand from the exact factors built into the tool (US cup = 240 mL). These are standard, physically meaningful conversions you can reproduce with any measuring equipment.
| From | Amount | To | Result |
|---|---|---|---|
| Cup | 1 | mL | 240.00 mL |
| Cup | 1 | oz | 8.47 oz |
| Cup | 2 | tbsp | 32.00 tbsp |
| tbsp | 3 | tsp | 9.00 tsp |
| mL | 250 | cup | 1.04 cups |
| oz | 4 | mL | 113.40 mL |
| g | 200 | mL | 200.00 mL |
A couple worth calling out: 1 cup → oz is 240 ÷ 28.35 = 8.47 oz, which is why a standard US measuring cup is often labeled “8 fl oz.” And 4 oz → mL is 4 × 28.35 = 113.40 mL, close to the common “half cup” of 120 mL that many recipes approximate.
Edge cases and rounding
- Grams vs. milliliters only match for water. 1 g equals 1 mL only for water-density liquids. Honey, oil, and flour have very different densities, so the gram conversion here is approximate for those ingredients. Use a weight-based converter for baking accuracy with dry goods.
- US cup vs. metric cup. This tool uses the US cup of 240 mL. A metric cup is 250 mL and an imperial cup is 284 mL, so results can differ by several percent if your recipe uses a different standard.
- Tiny amounts show more decimals. Because the tool increases precision for small results (e.g., a fraction of a teaspoon), you always get a usable figure rather than a rounded-off zero.
- Ounces here are fluid ounces of volume. This converter treats ounces as a volume measure (28.35 mL), not a weight. An ounce by weight is a different quantity, which is why separate weight converters exist.
- Very large batches. Converting a catering-scale recipe (say, 20 cups) works fine and stays readable with two decimal places.
Frequently Asked Questions
Frequently Asked Questions
How many tablespoons are in a cup?
There are 16 tablespoons in 1 US cup. This is a standard conversion used across most American recipes. If you need to convert the other way, 1 tablespoon equals 0.0625 cups (or roughly 1/16 of a cup).
Is 1 gram always equal to 1 milliliter?
Only for pure water at room temperature. For other ingredients, the conversion depends on density. For example, 1 gram of honey is about 0.7 mL, while 1 gram of oil is about 1.1 mL. This converter assumes water density for gram and ounce conversions, so it is most accurate for water-based liquids.
What is the difference between a US cup and a metric cup?
A US cup equals 240 mL (or 8 fluid ounces), while a metric cup is 250 mL. This converter uses the US cup standard (240 mL), which is the most common in American and many international recipes. British recipes sometimes use the imperial cup (284 mL), so always check which standard your recipe uses.
Can I use this converter for dry ingredients like flour or sugar?
This converter works best for liquids and water-density ingredients. For dry ingredients like flour, sugar, or rice, the weight-to-volume ratio varies significantly. For instance, 1 cup of all-purpose flour weighs about 120 grams, while 1 cup of granulated sugar weighs about 200 grams. For dry ingredients, we recommend using a dedicated cooking converter that accounts for ingredient density.
How many teaspoons are in a tablespoon?
There are 3 teaspoons in 1 tablespoon. This tool reflects that standard, so 1 tbsp converts to 3.00 tsp and 2 tbsp to 6.00 tsp. It's one of the most frequently used kitchen conversions when adjusting spice quantities.
Is the ounce in this tool fluid ounces or weight?
This converter treats ounces as fluid ounces of volume (28.35 mL), which is how liquids like milk or broth are measured in US recipes. An ounce by weight is a separate measurement and not interchangeable — that's why there is a dedicated weight converter for solids.
Can I use this to scale a recipe up or down?
Yes. Because the converter accepts any amount, you can easily scale quantities. To halve a recipe, just halve each ingredient value; to double it, double each value. The converter gives you the new unit-equivalent instantly, so you never have to recompute by hand.
Why does the result show extra decimals for small amounts?
For very small quantities, rounding to two decimals could hide important precision — for example, a fraction of a teaspoon matters in baking. The tool automatically switches to more decimal places for tiny results so you get a usable, accurate figure.
