What is CGPM?

CGPM is like a group of friends who decide how to measure things so everyone can agree.

Imagine you and your friends are playing a game where you have to share toys. If one person uses big blocks for counting, and another uses tiny pebbles, it gets confusing. That’s why the CGPM, short for Conférence Générale des Poids et Mesures, exists. It's like a group of leaders who make sure everyone agrees on how to measure things.

Every few years, people from around the world gather to talk about measurements. They’re not just talking about meters and kilograms, they’re making sure that when you use your ruler at school, it matches with rulers used in another country or even on a spaceship!

Think of it like setting rules for a game. If everyone agrees on how the game is played, it’s more fun and fair. The CGPM helps keep measurements consistent so scientists, engineers, and even kids can measure things accurately, no matter where they are in the world.
