ISO 31
ISO 31 is a set of rules that grown-ups like scientists and engineers uses to make sure everyone can understand the same measurements and units. Imagine if you want to talk about how long a pencil is, you could say it's 1 ruler long or 12 fingers long or 10 pencils long, but unless everyone agrees on which ruler or which fingers or which pencils we are using, we might all get confused.
So, ISO 31 helps us to agree on certain units for measuring length, weight, time, and other things that everyone can understand. For example, we all know that a centimeter is a small unit of length and a kilogram is a big unit of weight.
Using ISO 31, scientists and engineers can make accurate measurements and be sure that their findings can be compared with others around the world. It’s like a secret code or a special language that helps them understand complex things, just like your teacher who uses ABCs or 123s to teach you how to spell words and count numbers.
