Is 16 oz the same as 750ML?

Quick answer: No, 16 oz is not exactly the same as 750 ml. While their volumes are close, they are slightly different. 16 fluid ounces is equal to approximately 473 milliliters. 750 milliliters is equal to approximately 25.4 fluid ounces. So 750 ml contains a bit more volume than 16 oz.

This article will provide a detailed look at the relationship between ounces and milliliters and explain why 16 oz does not equate to exactly 750 ml. We’ll cover the definitions of fluid ounces and milliliters, how to convert between the two units, and look at the reasons for the discrepancy between 16 oz and 750 ml. Examples and tables are provided to help visualize and compare ounce and milliliter volumes.

What are Fluid Ounces and Milliliters?

Fluid ounces and milliliters are both units used to measure the volume of liquids.

Fluid ounces (abbreviated as fl oz or oz) are a customary unit of volume used in the United States. One fluid ounce is defined as exactly 1/128 of a US gallon.

Milliliters (abbreviated as mL) are a metric unit of volume. One milliliter is defined as exactly one cubic centimeter. The milliliter is 1/1000 of a liter, a base unit in the metric system.

So in summary:

– 1 fluid ounce = 1/128 US gallon
– 1 milliliter = 1 cubic centimeter

Some key differences between the two units:

– Fluid ounces are part of the customary US system of measurement
– Milliliters are part of the metric system used globally
– Milliliters relate to other metric units by factors of 10 while fluid ounces relate to gallons by factors of 2

Fluid Ounce and Milliliter Volumes

To get a sense of actual volumes, here are some comparisons:

– 1 fluid ounce is about 30 milliliters
– A typical “shot” of liquor is around 1 to 1.5 fluid ounces
– A 12 ounce can of soda contains approximately 355 milliliters
– 1 cup is 8 fluid ounces or approximately 237 milliliters

So while the ounce and milliliter volumes are different numerically, they represent similar real-world quantities. But the exact conversion ratios differ slightly, which is why 16 oz and 750 ml are not the same.

Converting Between Ounces and Milliliters

To accurately convert between fluid ounces and milliliters, you need to know the precise conversion factors:

– 1 fluid ounce = 29.5735 milliliters
– 1 milliliter = 0.033814 fluid ounces

So to convert fluid ounces to milliliters, multiply by 29.5735. To go the other way from milliliters to fluid ounces, multiply by 0.033814.

Let’s look at some examples:

Fluid Ounce to Milliliter Conversions

Fluid Ounces Milliliters
1 fl oz 29.5735 mL
8 fl oz (1 cup) 236.588 mL
16 fl oz (1 pint) 473.176 mL

Milliliter to Fluid Ounce Conversions

Milliliters Fluid Ounces
30 mL 1.01 fl oz
240 mL 8.12 fl oz
750 mL 25.36 fl oz

So while 750 mL converts to about 25.36 fluid ounces, 16 fluid ounces converts to 473.176 mL. Let’s take a closer look at why 16 oz and 750 ml are not equivalent.

The Difference Between 16 oz and 750 ml

Based on the conversion ratios, here is how 16 fluid oz and 750 ml actually compare:

– 16 fluid ounces = 473.176 milliliters
– 750 milliliters = 25.36 fluid ounces

So 16 fluid ounces is about 473 mL, while 750 mL is about 25 fluid ounces.

There is nearly a 3 ounce or 89 mL difference between the two amounts. 750 mL is a more round number when converting between metric units. But 750 mL corresponds to 25.36 fluid ounces, which is not an exact value in the imperial system.

The main reason for the discrepancy is that fluid ounces and milliliters are units from different measurement systems. While their volumes are similar in many cases, the conversion is not exact between the two units.

Comparing 16 oz and 750 ml

To visualize the difference, here is a simple table comparing 16 oz and 750 ml:

Volume Fluid Ounces Milliliters
16 fluid ounces 16 473
750 milliliters 25 750

So while they may seem equivalent at first glance, 16 oz and 750 ml have a measurable difference of about 3 fluid ounces or 89 mL.

When the Volumes are Equivalent

While 16 fluid ounces is not exactly equal to 750 ml, there are some cases where ounce and milliliter amounts correspond exactly:

– 1 fluid ounce = 30 milliliters
– 8 fluid ounces (1 cup) = 240 milliliters
– 128 fluid ounces (1 gallon) = 3785 milliliters

So fluid ounce and milliliter volumes align nicely for certain round numbers and common quantities. But due to the units coming from different measurement systems, there is often a slight discrepancy between conversions.


In summary, while 16 fluid ounces has a volume close to 750 milliliters, the two units are not equivalent. Because fluid ounces are part of the customary US system and milliliters are part of the metric system, conversions result in small differences in volumes. To accurately convert between units, you need to use the precise conversion factors of 1 fl oz = 29.5735 ml or 1 ml = 0.033814 fl oz. Knowing the definitions of fluid ounces and milliliters and being aware of the measurement system differences allows you to convert accurately and understand why 16 oz does not equal 750 ml. Paying attention to the units and using precise conversion factors is key when working with fluid volumes.
