Convert Ergs per Second to BTU per Second
Convert Ergs per Second (erg/s) to BTU per Second (BTU/s) instantly and accurately.
Conversion Formula
BTU/s = erg/s × 9.478171203e-11
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 Second
One BTU per second (BTU/s) ≈ 1,055 W - close to 1 kW but slightly larger. Used when heat rates are so high that per-hour or per-minute numbers become unwieldy. In fire protection engineering, large house fires peak at 500-2,000 BTU/s; industrial fires at millions of BTU/s. Blast characterisation for petrochemical safety and large industrial heat exchangers with duties of millions of BTU/h are conveniently expressed in BTU/s. Since 1 BTU/s ≈ 1.055 kW, conversion to SI is straightforward. 1 BTU/s = 1,055.056 W.
