What is an electron-volt (eV)?

An electron-volt is the energy gained by an electron when it moves through an electric potential difference of one volt; it is commonly used to describe energies at atomic and particle physics scales.

What does watt-hour (Wh) measure?

A watt-hour is a unit of energy representing the amount of work done or energy transferred by one watt of power sustained for one hour, commonly used for electrical energy quantification.

Why convert from electron-volt to watt-hour?

Converting from electron-volt to watt-hour helps relate microscopic energy scales from atomic or particle physics to practical electrical energy units used in technology and energy measurements.

Execute the conversion to obtain the equivalent energy in watt-hours.

Key Features

Converts electron-volt (eV) values to watt-hour (Wh) units accurately.
Supports energy conversions bridging microscopic atomic energies with practical electrical energy units.
Provides simple input and instant conversion results.

Examples

Convert 10 electron-volts to watt-hours: 10 eV equals approximately 4.45049065e-22 Wh.
Convert 1,000 electron-volts to watt-hours: 1,000 eV equals approximately 4.45049065e-20 Wh.

Common Use Cases

Describing photon and electron excitation energies in atomic-scale research.
Specifying semiconductor properties and carrier energies in electronics.
Analyzing particle and nuclear reaction energies in physics studies.
Relating particle-scale energies to electrical energy units for interdisciplinary applications.

Tips & Best Practices

Always verify that the scale of energy values is appropriate for conversion due to very small electron-volt magnitudes.
Use this converter for bridging microscopic energy units and macroscopic electrical units carefully considering their differing contexts.
Review conversion results with attention to numerical precision because values become extremely small after conversion.

Limitations

Electron-volt units represent extremely small-scale energy while watt-hour applies to larger-scale energy, so comparisons must consider scale differences.
The very small conversion factor can lead to minuscule output values requiring careful handling of numerical accuracy.
