ELI5: Explain Like I'm 5

Orders of magnitude (volume)

Have you ever seen a measuring cup in the kitchen? It's used to measure how much liquid you have. Sometimes you might measure a little bit of water for a recipe, and sometimes you might measure a lot of water to fill up a big pot. Orders of magnitude is like measuring how much water by looking at how many measuring cups you need to fill it up.

Let's say you have a small glass of water, like the size of a juice box. That's about one measuring cup, or one order of magnitude. But what if you wanted to measure a swimming pool full of water? That would require a LOT of measuring cups! Maybe even thousands or millions of cups! That's a much higher order of magnitude.

So orders of magnitude is just a way to talk about really big or really small things by comparing them to each other. It helps us understand how much of something there is by breaking it down into units of measurement.
