This song should help you to remember the units and the contrast between mass and weight (metric system). Mass involves the measure of the amount of matter in an object in grams (g) or kilograms (kg) and weight is the measure of gravity’s pull on an object in Newtons (N). The words are below:

Mass versus weight — two measures for an object.
They’re not the same, let’s all see why!
To determine the mass, we use a balance to do it.
We use a scale to measure weight.
Mass, measured in grams, or in kilograms,
It’s all about how much stuff – the object has!
Grams or kilograms (ba! ba! ba!)
They’re the units we use for mass. (for mass, for mass, for mass).
Newtons are for weight (ba! ba! ba!)
Weight’s the measure of gravity’s pull on the ob-ject.
So you can see, mass and weight aren’t the same thing.
Weight is the measure of gravity’s pull!
In contrast to weight, mass tells us how much matter,
How much matter the object has.
Mass, measured in grams, or in kilograms,
It’s all about how much stuff – the object has!
Grams or kilograms (ba! ba! ba!)
They’re the units we use for mass. (for mass, for mass, for mass).
Newtons are for weight (ba! ba! ba!)
Weight’s the measure of gravity’s pull on the ob-ject.
Mass and weight, mass and weight, they’re not the same.
Mass and weight, mass and weight, they’re not the same.
Mass and weight, they’re not the, not the same.
Grams or kilograms (ba! ba! ba!)
They’re the units we use for mass. (for mass, for mass, for mass).
Newtons are for weight (ba! ba! ba!)
Weight’s the measure of gravity’s pull on the ob-ject.
Yeah!
