Example: 16 fl oz (1 pint)
= 16 × 29.5735 = 473.2 mL
Example: 2 fl oz (medicine dose)
= 2 × 29.5735 = 59.1 mL

Fluid Ounce vs. Weight Ounce — Not the Same!
A fluid ounce (fl oz) measures volume, while an ounce (oz) measures weight. They are completely different units that happen to share the word "ounce":
- 1 fl oz of water weighs approximately 1.043 oz — close but not exact
- 1 fl oz of honey weighs about 1.5 oz (honey is denser than water)
- 1 fl oz of oil weighs about 0.95 oz (oil is lighter than water)
In recipes: "2 oz of chocolate" means weight (use a scale), while "2 fl oz of vanilla" means volume (use a measuring cup).
US Fluid Ounce vs. Imperial Fluid Ounce
| Type | Volume | Where Used |
|---|---|---|
| US Fluid Ounce | 29.5735 mL | United States |
| Imperial Fluid Ounce | 28.4131 mL | UK (historical) |
A US fluid ounce is about 4% larger than an Imperial fluid ounce. This converter uses the US fluid ounce.
What Is a Fluid Ounce?
A US fluid ounce (fl oz) is a unit of volume equal to 1/128 of a US gallon, 1/8 of a cup, or 29.5735 milliliters. It is the standard unit for measuring liquid volumes on nutrition labels, beverage containers, and medicine dosages in the United States.
What Is a Milliliter?
A milliliter (mL) is a metric unit of volume equal to 1/1,000 of a liter or 1 cubic centimeter (cc). It is used worldwide for measuring small liquid volumes, especially in medicine, science, and international cooking. Most US medicine doses are now labeled in both fl oz and mL.
