2. CGS, MKS, and FPS Systems: Alternate systems and their conversions.

Dimensions and Dimensional Analysis

1. Dimensional Formulae: Expression of physical quantities in terms of dimensions.

2. Applications:

• Checking dimensional consistency of equations.

• Deriving relationships among physical quantities.

Errors in Measurement

1. Types of Errors:

• Systematic Errors: Constant errors because of instruments or environment.

• Random Errors: Irregular variations.

• Least Count Error: Smallest measurable value of an instrument.

2. Propagation of Errors:

• Errors in addition, multiplication, subtraction, and division.

Significant Figures

1. Rules for determining significant figures.

2. Rounding off values and expressing results.

Measurement Techniques

1. Vernier Calipers: Measurement of length with least count accuracy.

2. Screw Gauge: Measurement of diameter or thickness of small objects.

3. Spherometer: Measurement of radii of spherical surfaces.

Practical Units

1. Light Year, Astronomical Unit, Parsec: Employed in astronomical measurements.

2. Angstrom, Fermi, Barn: Used for atomic and nuclear scales.
