When it comes to measuring volume, there are all sorts of units out there! Two common ones are liters and fluid ounces. Liters are part of the metric system, while fluid ounces are used in the United States customary system. So, what happens when you need to switch between the two?
That’s where this article comes in: We’re here to break down exactly how much oz are in a liter. We’ll cover the conversion factor and give you some easy ways to remember it, so you never have to guess again.
What are liters and fluid ounces?
Before we dive into the conversion, let’s define our terms.
What is a liter?
A liter is a unit of volume in the metric system. It’s equal to 1,000 milliliters, and it’s about the same as the volume of 1 kilogram of water at 4°C.
Liters are commonly used to measure beverages, cooking ingredients, and fuel. They’re also used in science and medicine.
What is a fluid ounce?
A fluid ounce is a unit of volume in the U.S. customary system. It’s related to other customary units like gallons, quarts, pints, cups, tablespoons, and teaspoons.
Fluid ounces are often used to measure drinks, cooking ingredients, and nutrition information. You’ll often see them used in bars and for cocktail recipes.
How many fluid ounces are in a liter?
Here’s the basic formula: 1 liter equals 33.814 U.S. fluid ounces. Keep in mind that this is approximate.
For everyday use, you can just round that up to 34 fluid ounces per liter.
That said, if you need a precise measurement – like when you’re cooking or baking – it’s important to use the exact conversion factor. Otherwise, you could throw off your recipe!
How to convert liters to fluid ounces (and vice versa)
Here’s how to convert liters to fluid ounces:
- Multiply the number of liters by 33.814 to arrive at the number of fluid ounces.
So, if you wanted to convert 2 liters to fluid ounces, the math would look like this: 2 L 33.814 fl oz/L = 67.628 fl oz.
And here’s how to convert fluid ounces to liters:
- Divide the number of fluid ounces by 33.814 to arrive at the number of liters.
So, if you wanted to convert 64 fluid ounces to liters, the math would look like this: 64 fl oz / 33.814 fl oz/L = about 1.89 liters.
Quick reference values
- ¼ L = 8.453 fl oz
- ½ L = 16.907 fl oz
- ¾ L = 25.361 fl oz
Practical applications: Hydration and daily water intake
It’s important to drink enough water every day to stay healthy. When you’re dehydrated, you might get headaches or feel tired, and other things can go wrong with your body.
Most adults need somewhere between 2 and 4 liters of water per day, which works out to roughly 67 to 135 ounces. But remember that your own needs may vary based on how active you are, the weather, and other factors.
Here are some easy ways to get more water into your daily routine:
- Use a larger water bottle so you can track how much you’re drinking.
- Carry a smaller water bottle with you so you can refill it throughout the day.
