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).
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.
How to convert kilowatt-hour (thermal) to electronvolts
1 kilowatt-hour (thermal) is equal to 2.24694327e+25 electronvolt when both are expressed in joule-equivalents:
1 kwh_th = (3,600,000 J ÷ 1.602176634e-19 J) ev = 2.24694327e+25 ev
Each kilowatt-hour (thermal) is defined as 3,600,000 J and each electronvolt as 1.602176634e-19 J in this tool, so one kwh_th equals 3,600,000 ÷ 1.602176634e-19 ev = 2.24694327e+25 ev.
Let d(kwh_th) be the numeric amount in Kilowatt-hour (thermal) (kwh_th), and d(ev) the amount in Electronvolt (ev). Then:
d(ev) = d(kwh_th) × (3,600,000 / 1.602176634e-19)
Equivalently, divide by how many kwh_th fit into one ev (joules per ev divided by joules per kwh_th):
d(ev) = d(kwh_th) ÷ 4.45049065e-26
Or: electronvolt = kilowatt-hour (thermal) ÷ 4.45049065e-26
Examples
Example #1: Convert 1 kwh_th to electronvolt
1 kwh_th = 1 kwh_th × (3,600,000/1.602176634e-19) ev = 2.24694326681e+25 ev
1 kwh_th = 1 kwh_th ÷ 4.45049065e-26 = 2.24694326681e+25 ev
Example #2: Convert 10 kwh_th to electronvolt
10 kwh_th = 10 kwh_th × (3,600,000/1.602176634e-19) ev = 2.24694326681e+26 ev
10 kwh_th = 10 kwh_th ÷ 4.45049065e-26 = 2.24694326681e+26 ev
Summary
To convert Kilowatt-hour (thermal) to Electronvolt, multiply the value in kwh_th by the ratio of joules per kwh_th divided by joules per ev. Equivalently: value_ev = value_kwh_th × (3600000 / 1.602176634e-19). Numerically, 1 kwh_th equals 2.2469432668058746e+25 ev.
Relationship context
You are converting between electrical energy (watt-hours) (Kilowatt-hour (thermal)) and atomic-scale energy (electronvolts) (Electronvolts). All values are mapped through joules first. The numeric factor is 2.246943e+25.
