Okay, let's imagine we want to talk about how much milk we have in a jug in France. In France, they use different units of measurement than we do in other parts of the world.
Instead of measuring the milk in cups or ounces, they use a unit called a "liter". A liter is like a big bottle - it holds a lot of liquid. Think of it like a really big juice box.
If we want to know exactly how much milk we have, we might use a smaller unit called a "milliliter". A milliliter is like a tiny drop of liquid - it doesn't hold very much at all. Think of it like a little rain drop in a really big puddle.
Now, let's say we want to measure something that isn't a liquid - like a length of rope. In France, they use a unit called a "meter". A meter is like a really long ruler - it helps us know how long something is. Think of it like a giant tape measure.
If we want to measure something even smaller, we might use a unit called a "centimeter". A centimeter is like a little piece of candy - it's very small. Think of it like a tiny little piece of a giant candy bar.
So, basically, France has their own special words and measurements for things like how much liquid is in a container or how long something is. It might be different than what we use in other parts of the world, but it's important to know so we can understand each other!
