Ever needed to switch between milliliters (mL) and fluid ounces (fl oz) while cooking, mixing a drink, or even doing a science experiment? It’s a pretty common need, especially when dealing with recipes that use different measurement systems.
So, just how many ounces are in 350 ml? This article will break down the conversion for you and give you a little more background on these units. Just remember, we’re talking about fluid ounces here—that’s volume, not weight!
Milliliters and fluid ounces defined
Before we get to the conversion, let’s define our terms.
What is a milliliter (mL)?
A milliliter is a unit of volume in the metric system. One milliliter is 1/1000th of a liter, or about 0.061 cubic inches. Another way to think of it is that 1 mL is the same as 1 cubic centimeter (cc).
What is a U.S. fluid ounce (fl oz)?
A U.S. fluid ounce is a unit of volume in the imperial system. There are 128 fluid ounces in a U.S. gallon.
Keep in mind that a U.S. fluid ounce isn’t the same as an ounce of weight, and it’s also different from an imperial fluid ounce.
The conversion: 350 mL to fluid ounces
So, how many ounces is 350 mL? The answer is about 11.83 U.S. fluid ounces. Keep in mind that unit conversions are rarely exact, so this is an approximation.
The conversion formula
If you want to convert other milliliter measurements to fluid ounces, here’s the formula you can use:
mL 0.033814 = fl oz
So, to convert 350 mL to fluid ounces, you’d multiply 350 by 0.033814, which equals 11.8349 fluid ounces.
Tools for conversion
If you don’t want to do the math yourself, there are plenty of online conversion tools and calculators that can give you an accurate answer. These tools are convenient and easy to use, so you can quickly convert milliliters to fluid ounces without having to worry about the calculations.
Volume vs. Weight: What’s the Difference?
Volume and weight aren’t the same thing, although we sometimes use them interchangeably in the kitchen. The characteristic that links volume and weight is density.
Density is the mass of a substance for each unit of volume. So, to convert from milliliters (a volume measurement) to ounces (a weight measurement), you need to know the density of the substance you’re measuring.
How to convert milliliters to ounces (weight)
The formula goes like this: To convert mL to ounces (weight), multiply the volume in mL by the density in oz/mL.
If you know the density in g/mL, divide by 28.3495 to get oz/mL before you do the calculation.
For example, water has a density of about 1 g/mL, while milk, oil, and other liquids have different densities.
Why accurate measurements matter
In cooking, using precise measurements can be critical to the outcome of a recipe. For that reason, measuring dry ingredients by weight is usually more accurate than measuring by volume because of variations in density.
In chemistry, volume conversions are essential for precise chemical reactions.
When do you need to convert between milliliters and ounces?
Converting between these two units of measure is a fairly common task. Here are a few instances where you might want to make the conversion.
Cooking and baking
Many recipes, especially those from outside the U.S., use metric measurements. If you’re more comfortable with ounces, you’ll need to convert to get the recipe right.
Scientific and medical uses
Accuracy is key in both science and medicine, so converting between milliliters and ounces is a task that should be done with care.
Everyday life
Whether you’re measuring detergent for the washing machine or mixing up a batch of weed killer, you may need to convert milliliters to ounces (or vice versa) at some point.
The Bottom Line
So, 350 milliliters is about 11.83 U.S. fluid ounces. Keep in mind that we’re talking about fluid ounces, which measure volume, not just ounces, which measure weight. It’s an easy mistake to make!
Whether you’re baking, cooking, or just curious, I hope this article helps you make quick, accurate conversions. Use the information here and the other resources I’ve mentioned to convert with confidence.
