Attovolt (aV) and Watt-hour (Wh) measure different electrical quantities. See how they relate and use context values for a physically meaningful result.
Context values
Some unit families need one extra value for a physically accurate result.
A watt-hour (Wh) is the electrical energy delivered by one watt sustained for one hour.
No fixed factor — different physical quantities
Attovolt measures electric potential (voltage) and Watt-hour measures electrical energy. These are different physical quantities, so there is no fixed multiplication factor between them. Use Ohm’s law and energy over time: V = I × R, P = V × I, E = P × time.

Compatibility notice
Attovolt (aV) measures electric potential (voltage). Watt-hour (Wh) measures electrical energy. Because these are different physical dimensions, there is no single fixed factor that converts one directly into the other — a numeric answer would be fabricated and misleading.
Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Enter voltage, current, resistance, and/or hours in the context fields above the result to get a physically accurate value based on the relationship between attovolt and watt-hour.
Conversion table
A direct numeric table is not shown here because attovolts and watt hours are not directly proportional. Instead, use the calculator above with context values, or convert within a single dimension using the related conversions below.

How attovolts and watt hours relate
Attovolt and Watt-hour belong to different electrical dimensions (electric potential (voltage) vs. electrical energy), so this page does not fabricate a fixed conversion formula. Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t). Supply the missing context (voltage, current, resistance, or time) in the calculator to compute a real-world equivalent.
Frequently asked questions
Can I convert attovolts directly to watt hours?
No. Attovolt measures electric potential (voltage) and Watt-hour measures electrical energy, so there is no fixed multiplication factor between them.
What is Attovolt (aV)?
An Attovolt (aV) equals 1e-18 volt(s), a scaled unit of electric potential used for atto-scale electrical work.
What is Watt-hour (Wh)?
A watt-hour (Wh) is the electrical energy delivered by one watt sustained for one hour.
How are attovolts and watt hours related electrically?
Related through Ohm's Law (V = I × R) and the power law (P = V × I), with energy linked to power over time (E = P × t).
How do I get a real number from this page?
Enter the known context values (such as voltage, current, resistance, or hours) in the calculator above. The Universal Converter will use Ohm's law and the power law to compute a physically accurate result.

About attovolts and watt hours
An Attovolt (aV) equals 1e-18 volt(s), a scaled unit of electric potential used for atto-scale electrical work. A watt-hour (Wh) is the electrical energy delivered by one watt sustained for one hour.
Because attovolt and watt-hour describe different electrical quantities, this page provides context-aware guidance instead of a fabricated formula. Use the calculator with real circuit values, or explore the related same-dimension conversions above for direct, exact conversions.
