This document discusses measurement in physics. It introduces the need for measurement and defines physical quantities. There are two types of physical quantities - fundamental and derived. Seven units make up the fundamental units used to measure the seven dimensions of the world: length, mass, time, temperature, amount of substance, electric current, and luminous intensity. Two supplementary units are also introduced. The document outlines different units for measuring length and defines the dimensions of physical quantities. It concludes by mentioning the least count of instruments used for measurement.
