Why Volume Conversions Are Important

If you ever need to measure liquids in the kitchen, you’ll want to understand the importance of conversions between milliliters and fluid ounces. It’s a common conversion, after all.

Cooking and Baking Accuracy

Ingredients are often measured by volume. If you don’t have the right unit of measurement, your dish might become too sweet, salty, or just all-around unpalatable. So taking the time to understand and convert each unit of measurement is essential if you want to get it right.

Calculating Serving Sizes

Measuring drinks and portions can be tricky without knowing how many ounces are in a certain milliliter amount. That’s why understanding conversions between milliliters and fluid ounces is important. So you know how much liquid is in a certain amount and can figure out accurate serving sizes for drinks or other liquids.

Understanding Recipes From Different Countries

Recipes from around the world often vary in terms of what units of measurement are used — like ml or fl oz. So conversions can come in handy if you’re trying to compare recipes from different parts of the world and don’t know how much one ml is equal in fl oz, then conversions can come in handy!

What is a Milliliter?

You might be wondering what a milliliter is. A milliliter or millilitre (symbol mL) is a unit of volume in the SI or metric system, where one milliliter equals one cubic centimeter or 0.03 fluid ounces. It is defined as being one thousandth of a litre or lieter.

A fluid ounce (abbreviated as oz) measures the same volume in the imperial system that a milliliter measures in the metric system of units, making it easier to exchange measurements between different types.

The metric to imperial ratio between milliliters and fluid ounces is one milliliter to 0.034 fluid ounces, with one fluid ounce equaling 29.5735 milliliters.

Knowing how many milliliters are in an ounce can make converting recipes and reading measurements easier when cooking or baking — plus, you’ll have fewer measuring cups lying around!

What is a US Fluid Ounce?

You may be wondering, what is a US fluid ounce? To simplify it, a US fl oz is a unit of measurement used to measure volume. It is equal to the volume of a circle or cylinder with a radius of one inch and a height of one inch. A fluid ounce is made up of about 29.6 milliliters, which is roughly the same size as one tablespoon.

When you convert from milliliters to fluid ounces, two main factors need to be taken into account:

  • Amount: How much do you need?
  • Unit: Do you have milliliters or fluid ounces?

Understanding these two variables will make it easy for you to convert from ml to oz accurately and quickly. The trickier part comes when you convert from larger amounts, such as liters or gallons, to smaller amounts, such as ml and oz. In this case, breaking down the process into smaller steps will make it easier for you.

This article talks about fluid ounces mainly used in the U.S., but there is also the Imperial fluid ounce. Accepted for use in the UK an Imperial ounce is slightly smaller at 28.4131 milliliters. For reference, there are 160 Imperial ounces in an Imperial gallon.

Milliliters Converted to Other Volume Units

You may also need to convert milliliters to other volume units. Although milliliters are typically used in metric measurements, other options are available. You can easily convert milliliters to liters, pints, quarts, or cups.


One liter is equal to 1,000 milliliters (mL). To convert from mL to l, divide by 1,000. For example, 200 mL = 0.2 L.


One pint is equal to 473.18 mL. So if you want to convert from mL to pints (pt), divide by 473.18. For example, 845 mL = 1.78 pt.


One quart is equal to 946.35 mL. To convert from mL to quarts (qt), divide by 946.35. For example, 3240 mL = 3.42 qt.


Cups equal 237 ml per cup, so if you want to convert from mL to cups, divide by 237. For example, 700 mL = 2 and a half cups (2 ½ cups).

Once you know how many milliliters are in a liter and how many other units are in a liter, converting milliliters into other volume units like liters or pints should be easy — especially if you use an online calculator!

How to Convert Ounces to Milliliters (oz to mL)

Converting oz to mL is also easy! You need to know a conversion factor and how to use it to make the conversion.

Step 1: Understand the Conversion Factor

The conversion factor is the relationship between a milliliter and an ounce. In the United States, one milliliter is equal to 0.033814 fluid ounces. This means 1 mL equals 0.033814 oz, while 1 oz equals 29.57353 mL.

Step 2: Use the Conversion Factor

To make your conversion, you’ll need to multiply or divide, depending on which direction you’re going in with your calculation.

For example, you want to convert 10 milliliters (mL) into ounces (oz). You’ll need to multiply 10mL by 0.033814oz/mL:

10 x .033814 = .33814 oz

So, 10 mL equals 0.313814 oz (rounded off from .33814).

On the other hand, let’s say you’d like to convert 20 ounces into milliliters. To do this, you’d divide 20oz by 0.033814oz/mL:

20 / .033814 = 593 mL

So, in this case, 20 oz equals 593 mL (rounded off from 592.788).

As you can see, converting between ml and oz requires some basic math skills—but once you understand the conversion factor, it’s really easy and quick!
