## Study Notes

### Measurement Standards

• The internationally accepted reference standard for measurement is called the System of International Units (SI).
• The units for the fundamental or base quantities are called base units.
• The units obtained for the derived quantities are called derived units.
• A complete set of both the base units and derived units is known as the SI system.

### Measurement of Physical Quantities

• The result of a measurement of a physical quantity is expressed by a numerical value and a unit of measurement.
• The measurement of any physical quantity involves comparison with a standard unit.

### Historical Systems of Units

• Three systems of units were in use extensively till recently: CGS (Centi-Gram-Second), FPS (Foot-Pound-Second), and MKS (Meter-Kilogram-Second).
