Hey there! Today we’re going to learn about **liters** and **fluid ounces**, which are both ways to measure how much liquid we have. This is important, especially for gardening, where we need to measure water for our plants!

Let’s start with what a **liter** is. It’s a unit of volume that we often use for liquids, like water. If you ever see a big bottle of soda, that’s usually about 1 liter.

Now, a **fluid ounce** is another way to measure liquid, but it’s smaller than a liter. In fact, 1 liter is equal to about 33.8 fluid ounces. That means if we want to know how many fluid ounces are in **4.5 liters**, we can do a little bit of math.

To find out, we can multiply the number of liters by the number of fluid ounces in a liter:

$$

4.5 \text{ liters} \times 33.8 \text{ fluid ounces/liter} = 151.5 \text{ fluid ounces}

$$

So, **4.5 liters** is the same as **151.5 fluid ounces**! This is super useful to know when you’re filling up a watering can or measuring how much water to give your plants.

Here are **7 objects** that would have the same amount of liquid as **4.5 liters** or **151.5 fluid ounces**:

- A large bottle of soda (2-liter bottle = 2 bottles = 4 liters)
- 3 standard-sized watering cans (each holds about 1.5 liters)
- 6 cups of water (1 cup = 8 fluid ounces, so 6 cups = 48 fluid ounces)
- A big pitcher that holds 4 liters of lemonade
- An average-sized bowl used for mixing ingredients (can hold about 1.5 liters)
- 2 quart-sized containers (1 quart = 32 fluid ounces, so 2 quarts = 64 fluid ounces)
- About 7 cans of soda (12 fluid ounces each, so 7 cans = 84 fluid ounces)

Now you know a bit about how measurements work and how to take care of your plants by measuring water correctly! Happy gardening! 🌱
