Convert Picowatts to BTU per Hour
Convert Picowatts (pW) to BTU per Hour (BTU/h) instantly and accurately.
Conversion Formula
BTU/h = pW × 3.412141633e-12
About Picowatts
A picowatt (pW) is 10⁻¹² W - the power scale of the most sensitive radio receivers. GPS satellites transmit 20-50 W; by the time that signal spans 20,000 km, the received power is ~0.1 pW (−130 dBm). Radio telescopes routinely detect cosmic signals in the picowatt range. Qubit control electronics in quantum computers must resolve energy differences at picowatt scales. Photodetectors in single-photon counting mode, hard drive head read-back signals at idle, and deep-shadow solar cells also operate at picowatt levels. 1 pW = 10⁻¹² W.
About BTU per Hour
One BTU per hour (BTU/h) ≈ 0.2931 W - the dominant HVAC capacity unit in the US and Canada. Room air conditioners are universally rated in BTU/h: 12,000 BTU/h = 1 ton of refrigeration = 3,517 W. Home furnaces range from 40,000-150,000 BTU/h. Office building cooling demand is calculated in BTU/h per ft². Engineers convert: BTU/h × 0.2931 = W; or W × 3.412 = BTU/h. 1 BTU/h = 0.29307 W.
