Question

What are the 22 derived quantities?

Answer 1

Derived quantities are physical quantities that are derived from fundamental quantities. The International System of Units (SI) recognizes several derived quantities, each with specific units. Here are 22 commonly referenced derived quantities:

1. **Area** (m²)
2. **Volume** (m³)
3. **Speed** (m/s)
4. **Velocity** (m/s)
5. **Acceleration** (m/s²)
6. **Force** (N or kg·m/s²)
7. **Pressure** (Pa or N/m²)
8. **Energy** (J or kg·m²/s²)
9. **Work** (J)
10. **Power** (W or J/s)
11. **Density** (kg/m³)
12. **Electric Charge** (C or A·s)
13. **Electric Potential** (V or J/C)
14. **Electric Field** (N/C or V/m)
15. **Magnetic Flux** (Wb or T·m²)
16. **Magnetic Field Strength** (T or N/(A·m))
17. **Frequency** (Hz or s⁻¹)
18. **Luminous Flux** (lm)
19. **Illuminance** (lx or lm/m²)
20. **Capacitance** (F or C/V)
21. **Inductance** (H or V·s/A)
