1. International System of Units

2. System of Units
 We use system of units to define certain physical
quantities
 To make methods of measurements universal we
use many conversion factors defined by System
of Units
 System of units is maintained by CGPM

3. Types of Systems of Unit
 M.K.S or metric system
 C.G.S or Centimeter – Grams- Second
 F.P.S or Foot-pound- Second

4. S.I or Metric System
 It is universally recognized and used system
 It is also known as Meter-Kilogram-Second or
MKS system
 It makes measurement convenient

5. C.G.S
 It is known as Centimeter-Gram-Second system
of unit
 It is user friendly with measurements when we
deal with microscopic world

6. F.P.S
 It is also known as Stroud system
 Foot-Pound-Second system of units is used in
defining many technical areas
