We also measure the mass of one heavier object in terms of other lighter objects
using a balance. Look at these pictures and fill in the boxes.
(a) (b) (c)
1 papaya weighs as 6 books weigh as 2 dolls weigh as much
much as 7 oranges. much as school as pencil boxes.
bag.
All these objects such as a cup, spoon, pebbles, blocks, etc., used for measurement
are called non-standard units of mass (weight).
Standard Units of Weight (Mass)
To measure the weight of objects accurately we use the standard units of weight.
Gram
The smaller unit of mass is gram. In short
it is written as g. It is used to measure the
weight of lighter objects such as an orange,
a soap bar, coin, etc. About 150 g About 100 g About 4 g
Kilogram
The standard unit of weight (mass) is
kilogram. In short it is written as kg.
It is used to measure the weight of heavy
objects such as bags of vegetables, boxes
of fruits, flour, rice, etc. About 1 kg About 10 kg About 25 kg
You can see the weights of grams and kilograms used for measuring weight while
buying vegetables and fruits.
If we put 1000 grams together, we get 1 kilogram. So, 1000 g = 1 kg
