Why Is Mass Measured in Kilograms While Weight Is Measured in Newtons?

Mass and weight are two ideas that often mix people up. Let's break it down in a simple way:

  • Mass is how much stuff is in an object. This amount stays the same no matter where you go in the universe. That’s why we use kilograms (kg) to measure it.

  • Weight is the pull of gravity on that mass. Because weight depends on gravity, it can change based on where you are (like the difference between the moon and Earth). We measure weight in newtons (N).

Here’s an easy formula that shows how they are related:

Weight = Mass × Gravity

So, remember: weight is a force, and mass is just how much stuff there is!
