Measurement of Weight

The weight of an object tells us “How heavy an object is".
In day-to-day life, weight is used to measure how much heavy the object is. The weight
of any object can be measured with the help of a balance and some known weights.

Units of Weight

Kilogram

The standard unit of weight is kilogram and it is denoted as ‘kg’.

For example, we measure the weight of a bag of rice in ‘kilograms’. We also measure our
own weight in 'kilograms'.

Gram
The smaller unit of weight is gram and it is denoted as ‘g’.

For example, we measure the weight of few apples, spices, etc. in grams.
