About Electronvolt

The electronvolt is the energy change of one elementary charge across 1 V: 1 eV ≈ 1.602176634×10⁻¹⁹ J (exact by SI definition). Used in particle physics and chemistry.

About Kilowatt Hour

One kilowatt-hour is the energy from 1 kW of power for one hour: 1 kWh = 3,600,000 J. Utility bills and battery specs often use kWh.

How to convert electronvolts to kilowatt hours

1 electronvolt is equal to 4.45049065e-26 kilowatt hour when both are expressed in joule-equivalents:

1 ev = (1.602176634e-19 J ÷ 3,600,000 J) kwh = 4.45049065e-26 kwh

Each electronvolt is defined as 1.602176634e-19 J and each kilowatt hour as 3,600,000 J in this tool, so one ev equals 1.602176634e-19 ÷ 3,600,000 kwh = 4.45049065e-26 kwh.

Let d(ev) be the numeric amount in Electronvolt (ev), and d(kwh) the amount in Kilowatt Hour (kwh). Then:

d(kwh) = d(ev) × (1.602176634e-19 / 3,600,000)

Equivalently, divide by how many ev fit into one kwh (joules per kwh divided by joules per ev):

d(kwh) = d(ev) ÷ 2.24694327e+25

Or: kilowatt hour = electronvolt ÷ 2.24694327e+25

Examples

Example #1: Convert 1 ev to kilowatt hour

1 ev = 1 ev × (1.602176634e-19/3,600,000) kwh = 0 kwh

1 ev = 1 ev ÷ 2.24694327e+25 = 0 kwh

Example #2: Convert 10 ev to kilowatt hour

10 ev = 10 ev × (1.602176634e-19/3,600,000) kwh = 0 kwh

10 ev = 10 ev ÷ 2.24694327e+25 = 0 kwh

Summary

To convert Electronvolt to Kilowatt Hour, multiply the value in ev by the ratio of joules per ev divided by joules per kwh. Equivalently: value_kwh = value_ev × (1.602176634e-19 / 3600000). Numerically, 1 ev equals 4.45049065e-26 kwh.

Relationship context

You are converting between atomic-scale energy (electronvolts) (Electronvolts) and electrical energy (watt-hours) (Kilowatt Hours). All values are mapped through joules first. The numeric factor is 4.450491e-26.
