Introduction

When you go to the shop to buy rice, sugar, pulses, kerosene or cooking
oil, the shopkeeper measures the amount or quantity of these things
as per your need. The cost of these things depends on their quantity
and the quantity is found out only after measurement. We measure
several things in our daily life. We use different instruments to

measure different things. For example, we measure the temperature
of our body with the thermometer, we measure the mass of the fruits
with a beam balance, we measure time with a watch or clock, etc.

We can measure most of the quantities whatever we talk about. The
quantities which can be measured are called physical quantities.
