In everyday life we usually compare the mass of different objects. We can compare the mass of two things by lifting or holding the objects with our hands and find out which object is heavier or lighter. But everything we can lift or hold and this type of measurement are not accurate, they are just rough estimates.

__Example:__If we hold pencil on one hand and book on other hand, we can easily say that book is heavier than the pencil.Measuring the mass of an object is also known as

__weighing the object.__We use different weighing scales or weighing machines to weigh objects.__In case of balance scale,__when two objects weigh the equal, the two pans of the weighing scales are said to be balanced and stay at the equal level and when one object heavy and other is lighter, the pan with the heavier object goes down and the pan with the lighter object goes up.We need to use suitable units to measure the masses of objects. The standard unit of mass is the gram. We write gram as ‘g’.

1000 grams put together make a bigger unit called

__kilogram__. Kilogram is written as ‘kg’ in short.1kg = 1000g

Or

1000g = 1kg

We measure lighter objects in grams whereas heavier objects in kilograms.

**Word Problem**__Example 1:__Three friends weigh 28 kg, 30 kg and 32 kg. Find their total weight.__Example 2:__Ria’s mom bought 3 kg grapes, 2 kg oranges, 2 kg apples and put them in her bag. Find the total weight of the fruits in her bag.**Download to practice offline.**
