Milliliters (mL) and fluid ounces (oz) are both ways to measure volume, but they’re part of different systems. You’ll often need to convert between the two in all sorts of situations, from following a recipe to understanding measurements in a science experiment.
Maybe you’re trying to measure out an ingredient, or perhaps you’re curious about the volume of liquid in a container. Whatever the reason, this article will tell you how to convert 9 mL to oz.
What is a milliliter?
A milliliter (mL) is a unit of volume in the metric system.
- One milliliter is the same as one cubic centimeter (cc).
- One milliliter is one-thousandth of a liter.
For reference, a milliliter is equal to about 0.061 cubic inches.
What’s a fluid ounce?
When measuring volume, you’ll often see amounts expressed in fluid ounces. But what exactly is a fluid ounce?
U.S. fluid ounce
In the U.S. system of measurement, a fluid ounce is a unit of volume that equals roughly 29.5735 milliliters. Think of it this way: a fluid ounce is 1/16 of a pint or 1/8 of a cup.
U.K. fluid ounce
It’s worth noting that a U.K. fluid ounce is a slightly different amount: 28.4130625 mL.
The conversion factor and formula
The conversion factor for milliliters (mL) to fluid ounces (oz) is:
1 mL = 0.03381402265 fl oz
To convert mL to fl oz, you can use this formula:
Ounces = Milliliters 0.03381402265
Keep in mind that this formula converts volume, not mass. If you want to convert mL (a volume measurement) to ounces as a weight measurement, you’ll need to know the density of the substance you’re measuring.
Okay, so how much is 9mL in fluid ounces?
Here’s the math:
9 mL multiplied by 0.03381402265 = 0.304 fluid ounces (approximately).
So, 9 mL is equal to about 0.304 fluid ounces.
Keep in mind that when you’re doing conversions like these, the final result is often rounded, depending on how precise you need to be.
Quick Conversion Table
Sometimes you need to know how many ounces are in a few more or less than 9 mL. Here’s a quick reference table for values close to 9 mL:
| Milliliters (mL) | Ounces (oz) |
|---|---|
| 9.0 mL | 0.304 oz |
| 9.1 mL | 0.308 oz |
| 9.2 mL | 0.311 oz |
| 9.3 mL | 0.314 oz |
| 9.4 mL | 0.318 oz |
| 9.5 mL | 0.321 oz |
| 9.6 mL | 0.325 oz |
| 9.7 mL | 0.328 oz |
| 9.8 mL | 0.331 oz |
| 9.9 mL | 0.335 oz |
Final Thoughts
So, to recap: 9 mL is about 0.304 fluid ounces. It’s a small amount, but sometimes, you need to be precise!
Understanding the differences between metric and customary measurement systems is key, especially when you’re dealing with recipes, medications, or scientific experiments.
