Supplementary Quantities and their Units

Supplementary quantities and their units a Most Important Topic for ITI Workshop Calculation and Science according to NCVT MIS NIMI Pattern to physic for ITI workshop calculation & science

In this chapter, we will understand the unit and its symbol of the area, volume, density, speed, acceleration, etc., as well as we will also know how many watts are there in 1 horsepower (HP) or 1 British horse power (BHP), etc. We will tell you about all types of units.
