Frequently asked questions

How many mL is 1 fluid ounce?

1 US fluid ounce equals 29.5735 millilitres exactly. So 8 fl oz (one US cup) is about 236.6 mL, and 16 fl oz (one pint) is about 473.2 mL. The converter uses this exact ratio for every calculation.

How many fluid ounces is 250 mL?

250 mL is approximately 8.45 US fluid ounces — slightly more than one US cup (which is 8 fl oz / 240 mL). 250 mL is also the size of one metric cup, which is why many international recipes use it as a standard measure.

Does this use US or UK fluid ounces?

US fluid ounces (1 fl oz = 29.5735 mL). UK / imperial fluid ounces are slightly larger (1 imperial fl oz = 28.41 mL) and used in some British recipes. If you're following a UK recipe and need imperial conversions, multiply our mL output by 0.0352 instead of using the result directly.

What's 1 cup in mL?

It depends on which cup. A US cup is 240 mL (8 US fl oz). A metric cup is 250 mL exactly. A UK cup is 284 mL (10 imperial fl oz). The converter's reference table includes both US and metric cups since most modern recipes use one of those two.

Can I convert mL to grams with this tool?

No — mL measures volume and grams measure weight. They're only equal for water (1 mL of water = 1 gram). For other liquids the density differs (1 mL of olive oil ≈ 0.92 grams; 1 mL of honey ≈ 1.42 grams). For ingredient-specific weight conversions, use a dedicated cooking weight calculator.

Is my input saved or sent anywhere?

No. The conversion runs entirely in your browser using JavaScript — nothing is sent to a server, logged, or stored. Once you close the tab, your inputs are gone.
