Cooking measurements without the mental math
Move between US kitchen volumes and metric milliliters in one clean, free tool.
Cooking measurements cross borders all the time. A US recipe may call for cups and tablespoons, a Canadian package may show milliliters, and a British source may use liters or fluid ounces. KitchenCalc puts those volume units on the same line so you can convert the amount you have into the amount your recipe needs. Choose a source unit, a target unit, and the number; the calculator shows both the direct result and the milliliter reference.
This tool uses 1 US cup = 236.588 milliliters and 1 US fluid ounce = 29.5735 milliliters. Tablespoons and teaspoons follow the same US system: one tablespoon is one-sixteenth of a cup and one teaspoon is one-forty-eighth. The values are precise enough for normal kitchen work, while the displayed result is rounded so it remains readable. For a very small amount, keep the extra decimals until the final step.
Volume is not weight. A cup of flour, a cup of water, and a cup of honey do not weigh the same, which is why the optional ingredient field stays separate from the main volume conversion. Select an ingredient only when you also want an estimated gram and ounce output. With no ingredient selected, the tool deliberately explains why it cannot give a meaningful weight instead of inventing a density.
For liquids, milliliters are usually easy to pour or measure with a marked jug. For dry ingredients, volume is more sensitive to settling and packing. If you are scaling a cake or bread formula, pair this converter with the Recipe Scaler and consider weighing flour for repeatability. The goal is not false precision; it is a clear, consistent bridge between the units in your kitchen.
Reference table
| Conversion | Approximate value |
|---|---|
| 1 US cup | 236.588 mL |
| 1 US fl oz | 29.5735 mL |
| 1 tbsp | 14.7868 mL |
| 1 tsp | 4.9289 mL |
| 1 liter | 1,000 mL |
Worked example
Example: 2 US fluid ounces equal 59.147 mL. If the ingredient is honey, that volume is about 85.1 g using 340 g per cup.
Frequently asked questions
Is a US fluid ounce the same as an ounce of weight?
No. A fluid ounce measures volume; a weight ounce measures mass. The ingredient choice is required before estimating weight.
Can I convert liters to cups?
Yes. Enter liters as the source and cups as the target; the same US volume factors are applied.
