Convert Picowatts to Exawatts
Convert Picowatts (pW) to Exawatts (EW) instantly and accurately.
Conversion Formula
EW = pW × 1.000000000e-30
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 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.
