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 (thermal)
Kilowatt-hour (thermal) is shown as a thermal-energy label and uses the same joule definition as kWh (3.6 MJ).
How to convert electronvolts to kilowatt-hour (thermal)
1 electronvolt is equal to 4.45049065e-26 kilowatt-hour (thermal) when both are expressed in joule-equivalents:
1 ev = (1.602176634e-19 J ÷ 3,600,000 J) kwh_th = 4.45049065e-26 kwh_th
Each electronvolt is defined as 1.602176634e-19 J and each kilowatt-hour (thermal) as 3,600,000 J in this tool, so one ev equals 1.602176634e-19 ÷ 3,600,000 kwh_th = 4.45049065e-26 kwh_th.
Let d(ev) be the numeric amount in Electronvolt (ev), and d(kwh_th) the amount in Kilowatt-hour (thermal) (kwh_th). Then:
d(kwh_th) = d(ev) × (1.602176634e-19 / 3,600,000)
Equivalently, divide by how many ev fit into one kwh_th (joules per kwh_th divided by joules per ev):
d(kwh_th) = d(ev) ÷ 2.24694327e+25
Or: kilowatt-hour (thermal) = electronvolt ÷ 2.24694327e+25
Examples
Example #1: Convert 1 ev to kilowatt-hour (thermal)
1 ev = 1 ev × (1.602176634e-19/3,600,000) kwh_th = 0 kwh_th
1 ev = 1 ev ÷ 2.24694327e+25 = 0 kwh_th
Example #2: Convert 10 ev to kilowatt-hour (thermal)
10 ev = 10 ev × (1.602176634e-19/3,600,000) kwh_th = 0 kwh_th
10 ev = 10 ev ÷ 2.24694327e+25 = 0 kwh_th
Summary
To convert Electronvolt to Kilowatt-hour (thermal), multiply the value in ev by the ratio of joules per ev divided by joules per kwh_th. Equivalently: value_kwh_th = value_ev × (1.602176634e-19 / 3600000). Numerically, 1 ev equals 4.45049065e-26 kwh_th.
Relationship context
You are converting between atomic-scale energy (electronvolts) (Electronvolts) and electrical energy (watt-hours) (Kilowatt-hour (thermal)). All values are mapped through joules first. The numeric factor is 4.450491e-26.
