Are you trying to find the KIPS 9th class Physics notes for the first chapter, Physical Quantities & Measurement, on the internet that you can download the PDF or images? Then you have come to the right place.

These are the notes that are helpful even you belong to Federal Board, Lahore Board, Faisalabad Board, Rawalpindi Board, Sargodha Board, Wah Board. Title: Physical Quantities & Measurement
This is the introduction to Physical Quantities & Measurement. The chapter starts with a brief introduction of measurements and the various measuring devices used for them. The different SI units and their symbols are also explained in this chapter.
The chapter further tries to explain the significant figures of the numbers which are required for measurement. It also explains what accuracy and precision is and how they are important while doing any kind of measurement.
The first thing to do in any science is to identify the quantities we wish to explain.
Every physical quantity is expressed as the product of a numerical value and a unit. Thus, the expression 5 m represents 5 metres, 25 kg represents 25 kilograms and so on. The numerical value of a physical quantity may be obtained by measurement. The unit for that particular physical quantity is defined arbitrarily and does not have a numerical value.
SI units: The SI or International System of Units is the most widely used system of units today. In this system, the fundamental or base units are used as the units for various other physical quantities. For example length is measured in metres, mass in kilograms and time in seconds.
CGS system: In this system, centimetre (cm), gram (g) and second (s) are used as base units for length, mass and time respectively.
