oz to ml Converter

Units of measurement have made life easier for everyone, allowing us to accurately measure food ingredients, liquids, and much more. However, it’s more important to understand how to convert these units of measurement, especially how to convert oz to ml.

To convert oz to ml, multiply the ounce by 28.4131 ml for British ounces and 29.5735 ml for US ounces. You can convert oz to ml much easier when you use the oz to ml converter. To use this converter, enter the value of oz you want to convert, and click ‘Convert’ to calculate its equivalent in ml.

It’s important to understand how to convert oz to ml when you’re a chef, a doctor, or anyone working with tiny solid and liquid sizes.

As such, this article will introduce you to the concept of ounces and milliliters, and show you how to convert oz to ml. You’ll learn how to do this with a formula and using our converter, as well as how to convert ml to oz.

What is a fluid ounce?

A fluid ounce is a unit of measurement for liquids, which is usually used in the US customary units system and the Imperial system of units. It’s perfect for situations where the liquid you want to measure is too small to use liters and too big to use milliliters. The fluid ounce is calibrated as fl oz or fl. oz.

While the fluid ounce is used in both the US customary units and the British Imperial system of units, the liquid sizes are different. The US fluid ounce is 1/128 of a US liquid gallon. The British fluid ounce is 8 fluid drams, or 1/160 of an imperial gallon, or 1/20 of an imperial pint.

To put it mathematically:

1 fl oz = 1/160 gal

1 fl oz = 1/128 gal

So the difference between both liquid sizes is roughly 4%, which isn’t much of a difference to the average person. However, for cases that require absolute accuracy, it’s something to take note of.

Bear in mind that the fluid ounce is not the same as the ounce. The ounce is a mass measurement unit, while the fluid ounce is a liquid measurement unit.

What is a ml?

The ml (or milliliter) is 0.001 liter or one-thousandth of a liter, which is roughly the size of a drop of water. It’s a unit of measurement for volume, just like the liter. This unit of measurement is usually used by doctors for medicine dosages, chefs in cooking recipes, and even in everyday tasks.

While the milliliter is used to measure volume, it’s not an official SI unit for volume; that honour belongs to the cubic meter. Nonetheless, a milliliter is equivalent to one cubic centimeter.

How many milliliters are in an ounce?

There’s no clear-cut answer here, as the ounce is a unit of measurement that depends on the density of a material. So, there are different milliliters in dry and wet materials, and this is something to take note of when you convert oz to ml.

Nonetheless, below is a table for when you convert oz to ml for different kitchen ingredients. This will give you an idea of how many milliliters are in an ounce for different substances.

What is an ounce?

The ounce is a unit of mass equal to 28.349523 grams, or 0.0625 pounds. It’s a British Imperial and US Customary unit of mass, and it can be abbreviated as oz.

We’ve already established that an ounce is a unit of measurement for mass, while the milliliter is for volume. However, the ounce is also used to measure liquid volume in countries like the United States.

That’s why you’ll notice that some liquid-based and packaged food products in the US and Britain are measured by the ounce.

Apart from being a unit of mass, the ounce can also be referred to as a unit of weight. This is because weight and mass are equivalent, as long as the calculation involving them is performed on Earth.

So, if an object weighs one ounce with a mass of one ounce on Earth, its mass on the Moon remains the same. However, its weight on the moon changes, and becomes ⅙ of an ounce.

One more thing of note is that the common ounce and the troy ounce are different. The troy ounce is 0.8333 (1/12) of a troy pound, while the common ounce is 0.0635 (1/16) of a regular pound.

How do you convert ounces to milliliters?

The first thing to keep in mind when you want to convert oz to ml is that there are two types of ounces.

  • British ounce: 1 British ounce is 28.4130 milliliters
  • US ounce: 1 US ounce is equal to 29.5735 milliliters

When you want to convert oz to ml for the British ounce, multiply the number of ounces you want to convert by 28.4131. For example, if you want to convert 15 ounces to milliliters, you multiply 15 by 28.4131.

15 x 28.4131 = 426.1965 ml

If you want to convert oz to ml for the US ounce, multiply the number of ounces you’ll be converting by 29.5735. So, if you want to convert 15 ounces to milliliters, you multiply 15 by 29.5735.

15 x 29.5735 = 443.6025 ml

Why we convert ounces to milliliters

There are many reasons why people convert oz to ml, and some of them are listed below:

  • Many Canadians convert oz to ml when cooking, as it makes it easier to measure many cooking ingredients.
  • Chemists and laboratory personnel convert oz to ml when trying to calculate the right sizes of chemicals for a reaction.
  • Doctors and other medical personnel convert oz to ml to ensure that they prescribe accurate drug doses for patients.
  • Air travellers also convert oz to ml to ensure that they’re carrying liquids and solids within the permitted limit.

How to convert milliliters to ounces

To convert ml to oz for any liquid, divide the ml you want to convert by 29.5735 to get its value in US ounces. If you want to get British ounces at the end of your ml to oz convert, divide the milliliters by 28.4131.

So, if you want to convert 50 milliliters to British ounces, divide your milliliters by 28.4131. If you want to get US ounces at the end of that conversion, divide the milliliters by 29.5735.

50/28.4131 = 1.7598 British ounces

50/29.5735 = 1.6907 US ounces

To put it simply, to convert ml to oz, you do the opposite of what you did when you convert oz to ml.
