Convert Milliliter to Fluid Ounce (ml → fl oz)

Converting milliliters to fluid ounces is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in milliliters

   Start with the number of milliliters (ml) you want to convert.
2. 2
   Multiply by 0.033814

   The conversion factor from ml to fl oz is 0.033814. Multiply your value by this number.
3. 3
   Read the result in fluid ounces

   The result is your value in fluid ounces (fl oz).

Multiply the value in milliliters by 0.033814. For the reverse direction, multiply by 29.57353.

• ✓1 ml = 1 cm³ exactly.
• ✓Medicine: teaspoon ≈ 5 ml, tablespoon ≈ 15 ml, shot glass ≈ 25 ml.
• ✓Measuring jugs marked in ml provide 2–5 ml accuracy; use a syringe below 10 ml.

• ✗Dosing liquid medication by kitchen spoon — spoons vary 3–8 ml. Use the supplied syringe.
• ✗Confusing ml (volume) with mg (mass) on medication labels — different units entirely.
• ✗Reading a "cc" measurement as cubic centimetre with different value — it is identical to ml.

What is the Milliliter?

The milliliter equals one thousandth of a liter (0.001 L) and is the standard small-volume unit for cooking, pharmaceuticals, cosmetics, and laboratory work. One milliliter is exactly 1 cubic centimeter (1 cm³), a convenient relationship: 1 mL of pure water weighs 1 gram. The milliliter is the universal unit on medicine bottles (a typical cough syrup dose is 5 mL), cosmetics (a perfume bottle is 50–100 mL), and recipe measurements outside North America (a tablespoon is 15 mL, a teaspoon is 5 mL). Medical syringes are calibrated in mL, and IV drip rates are computed in mL per hour. The milliliter relates to the liter (1,000 mL = 1 L), the cubic centimeter (1 mL = 1 cm³ = 1 cc), the teaspoon (1 tsp = 5 mL), and the US fluid ounce (1 fl oz ≈ 29.57 mL).

• Liquid medication dosing in syringes
• Precise cooking and baking measurements
• Laboratory reagent measurement

What is the Fluid Ounce?

The US fluid ounce equals exactly 29.5735295625 milliliters and is the standard small-volume unit for beverages, cocktails, personal-care products, and cooking in the United States. It is distinct from the (weight) ounce: 1 fluid ounce of water weighs about 1 ounce by weight at room temperature, but other liquids may weigh more or less. Soft-drink cans (12 fl oz), beer bottles (12 fl oz), shampoo bottles, and skin-cream tubs all label volume in fluid ounces. The US fluid ounce is slightly different from the UK imperial fluid ounce (28.4131 mL — about 4% smaller), reflecting the different gallon definitions. The US fl oz relates to the gallon (128 fl oz = 1 gal), the cup (8 fl oz = 1 cup), the tablespoon (2 tbsp = 1 fl oz), and the milliliter (1 fl oz ≈ 29.57 mL). Cocktail recipes universally use fluid ounces.

• Cosmetic and personal-care product volumes
