Convert Ergs per Second (erg/s) to BTU per Hour (BTU/h) instantly and accurately.
Conversion Formula
BTU/h = erg/s × 3.412141633e-7
About Ergs per Second
An erg per second (erg/s) is the CGS unit of power - exactly 10⁻⁷ W. Despite SI adoption, erg/s persists in astrophysics: the Sun's total luminosity is 3.828 × 10³³ erg/s; a peak supernova radiates ~10⁴³ erg/s - more power than the Sun emits over its 10-billion-year lifetime. X-ray binaries, active galactic nuclei, and neutron star accretion rates are catalogued in erg/s across decades of archival literature. 1 erg/s = 10⁻⁷ 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.
