Convert Kilovolts to Attovolts
Convert Kilovolts (kV) to Attovolts (aV) instantly and accurately.
Conversion Formula
aV = kV × 1.000000000e+21
About Kilovolts
The kilovolt (kV) equals 10³ V, used in high-voltage power supplies, X-ray machines, and electricity distribution. Dental and medical X-ray tubes operate at 60-120 kV; CRT television picture tubes required 20-30 kV for the final anode; distribution transformers step down from transmission lines at 11-33 kV to the local grid. Tesla coils generate sparks at tens to hundreds of kilovolts. 1 kV = 10³ V = 10⁻³ MV.
About Attovolts
The attovolt (aV) equals 10⁻¹⁸ V, representing the tiniest detectable voltage signals in quantum electronics. SQUID (Superconducting Quantum Interference Device) magnetometers in flux-locked-loop mode achieve sub-attovolt-equivalent noise floors; theoretical calculations of vacuum fluctuations in nanoscale Josephson junctions reference the attovolt range. 1 aV = 10⁻00b3 fV = 10⁻¹⁸ V.
