Metric Volume Standard

What is a ml?

A milliliter (mL) is a metric unit of volume equal to one-thousandth of a liter (0.001 L) or one cubic centimeter (1 cm³).

SI Unit Derivation
0.001 Liters (L)

The milliliter is an accepted non-SI metric unit derived from the International System of Units (SI) base unit of cubic meter (m³).

Cubic Geometry
1 cm³ (1 cc)

Represents a 3-dimensional cube measuring exactly 1 centimeter on each edge (1 cm × 1 cm × 1 cm), which equals 0.0610237 cubic inches (cu in).

Water Mass Link
1.000 Gram (g)

At 3.98 °C (maximum water density), 1 mL of pure distilled water has a mass of exactly 1 gram, creating a direct link between volume and mass.

Historical Origin
Litron (1795)

Adopted during the French Revolution in 1795, replacing the royalist volume measure called the litron with a decimal metric system.

What is a fluid oz?

A fluid ounce (fl oz) is a unit of liquid volume in the United States Customary Units (USCU) and the British Imperial system.

Standard 1: US Customary (fl oz)
29.5735 mL

Defined by the National Institute of Standards and Technology (NIST) as exactly 1/128 of a US liquid gallon. The US liquid gallon is legally based on the historic English Queen Anne wine gallon of 1707 (231 cubic inches).

Usage: United States recipes, beverages, and liquid commerce.
Standard 2: British Imperial (fl oz)
28.4131 mL

Defined by the British Imperial Weights and Measures Act of 1824 as exactly 1/160 of an Imperial gallon. An Imperial gallon was originally formulated as the space occupied by 10 pounds of distilled water weighed in air at 62 °F.

Usage: United Kingdom, Canada, Australia, and Commonwealth nations.
Standard 3: US Food and Drug Administration (FDA)
30.0000 mL

Under 21 CFR 101.9, the United States FDA legally defines one fluid ounce as exactly 30 milliliters specifically for nutrition fact labeling.

Usage: Packaged food and nutrition fact panels.
⚖️

Crucial Distinction: Fluid Ounces (Volume) vs Ounces (Weight)

A fluid ounce (fl oz) measures liquid volume (the physical space occupied by a liquid), whereas an avoirdupois ounce (oz) measures mass or weight. One avoirdupois ounce is equal to 28.3495 grams. Only for pure water at 4 °C does 1 US fluid ounce weigh approximately 1.043 dry ounces; denser liquids like honey weigh up to 1.42 dry ounces per fluid ounce.

Formulas & Step-by-Step

How to Convert ML to OZ

To convert milliliters (mL) to fluid ounces (fl oz), divide the volume in milliliters by 29.5735 for US fluid ounces, or divide by 28.4131 for UK Imperial fluid ounces.

Divide milliliters by 29.5735, if converting to US customary fluid ounces. Divide milliliters by 28.4131, if converting to British Imperial fluid ounces.

US Customary Formula Division Standard
fl oz (US) = mL ÷ 29.57352956
Alternative Multiplication: fl oz = mL × 0.03381402
British Imperial Formula Imperial Standard
fl oz (UK) = mL ÷ 28.41306250
Alternative Multiplication: fl oz = mL × 0.03519508

FAQs

Clear, verified answers to common volume conversion questions between milliliters and fluid ounces.

How to convert oz to ml

To convert fluid ounces (fl oz) to milliliters (mL), multiply the volume in fluid ounces by 29.5735 for US customary ounces, or multiply by 28.4131 for UK Imperial fluid ounces. For example, 8 US fl oz multiplied by 29.5735 equals 236.588 mL (0.237 L).

How do you convert milliliters to ounces?

You convert milliliters to ounces by dividing the milliliter volume by 29.5735 for US customary fluid ounces, or by dividing by 28.4131 for UK Imperial fluid ounces. For example, 500 mL divided by 29.5735 equals 16.907 US fl oz (0.50 L).

How to convert 8 oz to ml?

To convert 8 oz to ml, multiply 8 by 29.5735 to get 236.588 mL for US customary fluid ounces, or multiply 8 by 28.4131 to get 227.305 mL for UK Imperial fluid ounces. In everyday cooking, 8 US fluid ounces represents exactly 1 standard US cup.

How many milliliters make 8 ounces?

There are 236.588 milliliters in 8 US fluid ounces, and 227.305 milliliters in 8 UK Imperial fluid ounces. For packaged food in the United States, FDA nutrition regulations round 8 fluid ounces to 240 mL.

How many ounces are in 100 ml?

There are 3.3814 US fluid ounces or 3.5195 UK Imperial fluid ounces in 100 ml. This measurement equals 0.10 liters (L) or 6.76 standard tablespoons.

How many ounces are in 750 ml?

There are 25.3605 US fluid ounces or 26.3963 UK Imperial fluid ounces in 750 ml. A volume of 750 mL (0.75 L) represents the standard worldwide bottle size for wine and spirits.

Is a US fluid ounce the same as a UK fluid ounce?

No, a US fluid ounce is not the same as a UK fluid ounce. A US fluid ounce equals 29.5735 mL, whereas a UK Imperial fluid ounce equals 28.4131 mL. A US fluid ounce is 4.08% larger than a UK Imperial fluid ounce.

Can milliliters be converted to ounces by weight?

Yes, milliliters can be converted to ounces by weight if the density of the liquid is known. For pure water with a density of 1.00 g/mL at 4 °C, 100 mL weighs 100 grams, which equals 3.5274 avoirdupois ounces (oz) of weight.

Can I use an ML to OZ calculator for water and milk?

Yes, you can use an ML to OZ calculator for water and milk when converting liquid volume. Both liquids occupy space in milliliters and fluid ounces regardless of density. Whole cow milk has a density of 1.03 g/mL, making 240 mL weigh 247.2 g, but its liquid volume remains 8.115 US fl oz.

Is there an ML to OZ calculator app?

Yes, this web application functions as an installable progressive web app (PWA) and runs in any modern web browser on iOS, Android, macOS, and Windows without downloading separate app store software. Save this website to your device home screen for immediate offline-capable access.
