ml to oz Converter

In real-world settings whether you are preparing a recipe, measuring liquid medicine, or analyzing lab results you will often need to convert milliliters (ml) to fluid ounces (fl oz). To do this accurately, it is important to understand the units involved and recognize that not all fluid ounces are the same.

What Is a Milliliter (ml)?

A milliliter is a unit of volume in the metric system. It represents one-thousandth of a liter and is widely used around the world in scientific, medical, and culinary fields.

• 1 milliliter = 0.0338 fluid ounce
• Visually, 1 ml is approximately 20 drops of water or about 0.2 teaspoons

What Is a Fluid Ounce (fl oz)?

A fluid ounce is a volume unit used primarily in the United States and the United Kingdom, though the actual amount differs slightly between the two systems (metric & imperial).

• 1 U.S. fluid ounce = 29.5735 milliliters
• 1 UK (Imperial) fluid ounce = 28.4131 milliliters

This distinction is critical when converting from milliliters to ounces. Always know which system you're working with.

How to Convert ml to oz

To convert milliliters to ounces, we perform division using the respective conversion factor for the measurement system.

U.S. Fluid Ounce Formula

If you are using U.S. measurements, use the following formula:

U.S fl oz = ml / 29.5735

Example: Suppose you have 100 ml of orange juice and want to convert that in U.S. fluid ounces:

100 / 29.5735 = 3.38 U.S. fl oz

So, 100 ml = 3.38 U.S. fluid ounces

UK (Imperial) Fluid Ounce Formula

For UK or Imperial measurements, use this formula:

UK fl oz = Milliliters (ml) / 28.4131

Example: Let's say you have 150 ml of milk for a British recipe. You would calculate:

150 / 28.4131 = 5.28 UK fl oz

So, 150 ml = 5.28 UK fluid ounces
