Electronvolts to Watt-hours Conversion
Enter the energy in electronvolts below to get the value converted to watt-hours.
How to Convert Electronvolts to Watt-hours
To convert an electronvolt measurement to a watt-hour measurement, multiply the energy by the conversion ratio. One electronvolt is equal to 4.4505E-23 watt-hours, so use this simple formula to convert:
The energy in watt-hours is equal to the electronvolts multiplied by 4.4505E-23.
Electronvolts and watt-hours are both units used to measure energy. Keep reading to learn more about each unit of measure.
Electronvolts
The electronvolt is a unit of energy used in physics, most commonly in electrostatic particle accelerator sciences.
Electronvolts can be abbreviated as eV; for example, 1 electronvolt can be written as 1 eV.
Energy in electronvolts can be expressed using the following formula: E = qV
The energy E in electronvolts is equal to the electric charge q in elementary charge times the potential difference V in volts.
Watt-hours
The watt-hour is a measure of electrical energy equal to one watt of power over a one hour period.
Watt-hours are usually abbreviated as Wh, although the formally adopted expression is W·h. The abbreviation W h is also sometimes used. For example, 1 watt-hour can be written as 1 Wh, 1 W·h, or 1 W h.
In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.[1]
