So, imagine you want to do some cooking with your mom or dad. You need to know how much of each ingredient you should use, right? That's where measures come in.
Measures are basically the tools we use to measure things like weight, volume and length. And when we talk about "mesures usuelles" we mean the most commonly used measures in France.
Let's start with weight. When we want to measure how heavy something is, we use what's called a balance, which is like a scale with two pans. The most common unit of weight in France is the gram, which is very small. For example, a grape weighs around 5 grams.
Next, we have volume, which is how much space something takes up. To measure volume, we use things like cups, spoons, liters, and milliliters.
For example, when we want to measure liquid like milk or water, we use a measuring cup. The most common unit of volume in France is the liter, which is like a big bottle of water.
Finally, there's length. This is how long or tall something is. To measure length, we use units like meters, centimeters, and millimeters.
For example, if we want to know how tall someone is, we could use a measuring tape to find out. In France, the most common unit of length is the meter, which is about as long as three big steps.
So, in summary, mesures usuelles are the most commonly used measures in France, which include units of weight, volume, and length like grams, liters, and meters. These measures help us cook, build things, and measure our world!
