Formulas

1. Units and Measurement

Physical quantity = (numerical value) × (unit)

L.C. = x/n

L.C. = Pitch of screw / Total number of divisions on circular scale

Correct reading = Observed reading - Zero error (with sign)

2. Length Units and Their Conversions

1 m = 100 cm

1 m = 1000 mm

1 μm = 10^-6 m

1 nm = 10^-9 m

1 f = 10^-15 m

3. Mass Units and Conversions

1 g = 10^-3 kg

1 mg = 10^-6 kg

1 quintal = 100 kg

1 metric tonne = 1000 kg

1 u = 1.66 × 10^-27 kg

4. Time Units and Calendar Facts

1 min = 60 s

1 h = 3600 s

1 day = 86400 s

1 year = 365 days = 3.1536 × 10^7 s

1 leap year = 366 days
