Common Scenarios

Power conversion is frequently used in automotive manufacturing, appliance purchases, and air conditioning. Car enthusiasts compare kilowatts (kW) and horsepower (hp). When choosing AC units, understanding "tons of refrigeration (TR)" is necessary.

History & Background

The concept of power originated in the Industrial Revolution. After James Watt improved the steam engine, he proposed "horsepower" to demonstrate its efficiency. Later, to honor him, physics named the power of one joule per second a "watt" (W).

Conversion Details

Power conversion is based on the watt (W), representing work done per unit time.

Common conversions: 1 hp ≈ 745.7 W, 1 metric hp ≈ 735.5 W, 1 kW ≈ 1.341 hp.
