What is the metric unit for measuring mass?

Metric Mass

Mass: how much matter or stuff is in an object.
Many people think mass and weight are the same but they are not.

Your weight is how strong gravity is pulling on it.
Metric Mass is a measure of the amount of matter in an object and the object's ability to resist acceleration.

Many people think weight is the same everywhere most likely because we all live on the surface of the planet Earth!

An object's mass doesn't change but its weight can change according to the gravitational pull.
Your weight is less on the moon

Grams
Kilograms
Tonnes
These three units are the most common measurements of mass in the metric system.

The SI base unit of mass is the kilogram

A gram, which is written with a g, weighs about the same as a paper clip.

1 pound is equal to 453.5 grams

1000 grams equal a kilogram
1 kilogram equals 2.2 pounds.
Think of a textbook

1000 kilograms equals a tonne which also called a metric ton
1 tonne = 2204 pounds
An average car has a mass of about 2 tonnes
