Convert BTU per Second to Exawatts
Convert BTU per Second (BTU/s) to Exawatts (EW) instantly and accurately.
Conversion Formula
EW = BTU/s × 1.055055853e-15
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.
About Exawatts
An exawatt (EW) is 10¹⁸ W. The Sun's total luminosity is 3.828 × 10²⁶ W = 3.828 × 10⁸ EW. Earth intercepts ~0.174 EW of solar power. Gamma-ray burst peak luminosities reach 10⁶-10¹ EW, making them the most powerful transients in the universe. Soft gamma-repeater (magnetar) giant flares briefly reach ~10⁵ EW. Proposed multi-exawatt laser projects (IZEST initiative) aim to compress kilojoules into attosecond pulses for QED vacuum physics. Global human civilisation consumes ~1.8 × 10⁻² EW (18 TW). 1 EW = 10¹⁸ W.
