### Measuring Mass | Addition and Subtraction of Mass

We’ll talk about about measuring mass. We all know that, after we put two objects in a stability scale, the pan with heavier objects all the time drops downwards and the pan with lighter object goes up. So, we are able to evaluate weights of two completely different objects utilizing a stability and say which is heavier.

A ball and a marble are positioned on the 2 sides of a balancing scale. We see that the ball goes down. So it’s heavier. The marble strikes up as a result of it’s lighter. So, within the scale, the pan carrying the heavier object strikes down and the pan carrying the lighter object strikes up.

We maintain including extra marbles till the 2 pans of the balancing scale are on the identical stage. We are saying that each the ball and the marbles weigh the identical now.

From the above, we are able to see that the ball weighs the identical because the 4 marbles. To learn how heavy an object is, we have to weigh the article or measure the mass of the article.

Kilogram and Gram:

Kilogram is the usual unit for measuring mass. Kilogram is written as kg. We use kg to weigh heavier objects. We measure lighter objects in grams.

We all know the vegetable vendor is weighing potatoes in kilogram. The goldsmith is weighing a hoop in grams. The wheat luggage are weighing in quintals.

Among the following weights are used like 10 kg, 5 kg, 2
kg, 1 kg, 500 g, 200 g, 100 g, 50 g and so forth.

The unit of weight is the gram. Kilogram is an even bigger unit of weight.

1 kilogram is the same as 1000 grams

or

1000 grams is the same as 1 kilogram

We write gram as ‘g’ and kilogram as ‘kg’ briefly kind.

1 kg is the same as 1000 g

or

1000 g is the same as 1 kg

Kilogram is the usual unit for measuring mass. Kilogram is written as kg. We use kg to weigh heavier objects. We measure lighter objects in grams.
