In class 11 student will explore the topic of units and measurement in chapter 2 of the physics textbook. However, the main objective of the chapter is to help students get familiar with topics like SI units, significant figures, a combination of errors, the dimension of a physical quantity, dimension formula and equation, absolute error and they will also learn about the measurement of length, mass and time. As there are many topics to cover and at the same time understand them clearly students need to study smartly.
And to do just that, we at Byju’s are providing class 11 physics chapter 2 notes which will help students in quickly grasping the concepts and make the most out of their study time. The CBSE notes are designed by the experts to provide a complete overview of the chapter in an easy manner using simple language and format. These notes also contain detailed explanations for each topic and will enable students to prepare effectively for the exams.

In physics, there are various common systems of units to measure quantities, they are:
- FPS system
- CGS system
- MKS system
- SI system
SI units of International Systems of units are a standardized set of units universally. The units which can be used to measure some of the physical quantities are kilogram, metre, ampere, second, mole, kelvin, candela.
