About Watts

The watt (W) is the SI unit of power - 1 J/s - named after James Watt (1736-1819). Familiar power levels: smartphone charging 5-65 W; laptop 15-100 W; microwave 700-1,200 W; electric kettle 2,000-3,000 W; human resting metabolism ~80 W; peak sprint ~2,000 W. The now-obsolete 100 W incandescent bulb is replaced by a 10-15 W LED producing the same light. In AC circuits, reactive power uses the var and apparent power the VA, both derived from watts. 1 W = 1 J/s = 1 kg·m²/s³.

About BTU per Minute

One BTU per minute (BTU/min) ≈ 17.58 W. Fire engineering uses BTU/min for heat release rate (HRR): a burning sofa releases 500-5,000 BTU/min; a flashover room fire 50,000-500,000 BTU/min. US commercial gas burners are rated 500-2,000 BTU/min. NFPA fire suppression standards use BTU/min to match sprinkler flow to HRR. Industrial furnace heating cycles also use this unit. 1 BTU/min = 17.584 W.
