Convert BTU per Hour to Exawatts
Convert BTU per Hour (BTU/h) to Exawatts (EW) instantly and accurately.
Conversion Formula
EW = BTU/h × 2.930710702e-19
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.
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.
