About the Btu/hour
Facts & Uses
- Standard power rating in HVAC (heating, ventilation, air conditioning) systems.
- Air conditioners and furnaces are often rated in Btu/h or tons of refrigeration (1 ton = 12,000 Btu/h).
- Useful for comparing cooling capacities or fuel efficiencies.
Curiosities
- 1 Btu/h = 0.293071 W — a 12,000 Btu/h air conditioner is roughly 3.52 kW.
- MBH (1000 Btu/h) is a common shorthand in U.S. equipment specs.
About the Watt
Facts & Uses
- Named after James Watt, inventor of the improved steam engine.
- Core SI unit for power — rate of energy transfer per second.
- Used universally in physics, electronics, and engineering.
Curiosities
- A human at rest emits about 100 W of heat.
- Modern LED lamps use 5–15 W with similar brightness to 60–100 W incandescent bulbs.
