About US fluid ounce (us fl oz)
The US fluid ounce (fl oz) is a unit of volume equal to approximately 29.574 milliliters, one sixteenth of a US liquid pint. It is the primary small-volume unit on US food labels, beverage cans, and pharmaceutical liquid measurements. A standard US soda can is 12 fl oz; a coffee shop "tall" is 12 fl oz; a standard shot is 1.5 fl oz. The US fluid ounce is distinct from the imperial fluid ounce (28.413 mL) and should not be confused with the ounce as a unit of mass.
A US soda can is 12 fl oz (355 mL). A US shot glass holds 1.5 fl oz (44 mL). A US water bottle is commonly 16.9 fl oz (500 mL).
About Milliliter (ml)
A milliliter (mL) is one thousandth of a liter (0.001 L), exactly equal to one cubic centimeter (1 cm³). It is the most widely used small volume unit in medicine, cooking, and science. Drug dosages are prescribed in milliliters, soft drink cans are 330 mL, and laboratory pipettes measure in mL. The milliliter bridges the gap between the impractically small microliter and the everyday liter, making it the default unit for liquid measurement in clinical and domestic settings worldwide.
A standard medicine syringe holds 1–20 mL. A teaspoon is approximately 5 mL. A typical espresso shot is 30 mL.
Etymology: From Latin "mille" (thousand) + "liter". The prefix milli- denotes 10⁻³ in the SI system.
US fluid ounce – Frequently Asked Questions
What is the difference between a fluid ounce and an ounce?
A fluid ounce (fl oz) is a unit of volume; an ounce (oz) is a unit of mass/weight. One US fluid ounce of water happens to weigh approximately 1.04 avoirdupois ounces — close but not equal. For other liquids, the mass per fl oz varies with density.
How many fluid ounces are in a US cup?
There are exactly 8 US fluid ounces in one US cup (240 mL). A pint is 16 fl oz, a quart is 32 fl oz, and a gallon is 128 fl oz.
What is the difference between US and imperial fluid ounces?
A US fluid ounce is approximately 29.574 mL; an imperial (UK) fluid ounce is approximately 28.413 mL — about 4% smaller. A US pint (16 fl oz) is 473 mL while a UK pint (20 fl oz) is 568 mL, a 20% difference that significantly affects beverage serving sizes.
How many fluid ounces are in a standard water bottle?
The most common US bottled water size is 16.9 fl oz (500 mL). Other sizes include 8 fl oz (237 mL), 20 fl oz (591 mL), and 33.8 fl oz (1 liter).
How many fl oz are in a standard US wine pour?
A standard US restaurant wine pour is 5 fl oz (148 mL). A 750 mL wine bottle yields approximately 5 pours of 5 fl oz each.
Milliliter – Frequently Asked Questions
How many milliliters are in a teaspoon?
One US teaspoon equals approximately 4.93 mL, conventionally rounded to 5 mL in cooking and medicine. An Australian/metric teaspoon is exactly 5 mL. A tablespoon is 15 mL (3 teaspoons).
Why do medicine bottles say "do not use household spoons" for dosing?
Household teaspoons and tablespoons vary wildly — from 3 to 7 mL for a "teaspoon" depending on the design. A parent dosing 2.5 mL of infant paracetamol with a large decorative spoon might accidentally give double the intended dose. Studies have shown dosing errors of 20–50% when using kitchen cutlery. Calibrated oral syringes (marked in 0.1 mL increments) eliminate this problem entirely, which is why the AAP and WHO both recommend them over any spoon for liquid medications.
How many milliliters are in a standard drink can?
A standard soft drink or beer can is typically 330 mL in Europe and 355 mL (12 US fl oz) in the United States. A 500 mL can is common for beer in many markets.
What is a standard medical dose in mL?
Common oral liquid medications are dosed at 2.5, 5, or 10 mL. Injectable medications may be 0.1–2 mL. IV fluid bags are typically 100, 250, 500, or 1,000 mL.
How many milliliters are in a fluid ounce?
One US fluid ounce equals approximately 29.57 mL. One imperial (UK) fluid ounce equals approximately 28.41 mL. The two are close but not identical — important for recipes crossing US and UK sources.
