Examples
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Mixing metric horsepower with mechanical horsepower; prefer kW for consistency.
About Power
Power is the rate of energy transfer (J/s). Watts and kilowatts dominate, with horsepower used historically in vehicles and machinery. Choosing kW vs hp is often a matter of audience and regulation.
About Watt (W)
Watt (W)
