Kiloelectronvolts to Joules: 1 keV equals 1.60218e-16 J. To convert kiloelectronvolts to joules, multiply by 1.60218e-16 (J = keV × 1.6022e-16). For example, 10 keV = 1.60218e-15 J.
How to Convert Kiloelectronvolts to Joules
To convert from kiloelectronvolts to joules, multiply the value by 1.60218e-16. The conversion is linear, meaning doubling the input doubles the output.
Conversion Formula
- Kiloelectronvolts to Joules:
J = keV × 1.6022e-16 - Joules to Kiloelectronvolts:
keV = J ÷ 1.6022e-16

Understanding the Units
What is a Kiloelectronvolt?
A kiloelectronvolt equals 1,000 electronvolts (10³ eV).
Common contexts: X-ray energy, nuclear medicine.
What is a Joule?
The joule is the SI derived unit of energy, equal to the work done by a force of one newton acting through a distance of one meter (1 J = 1 N·m = 1 W·s).
Named after James Prescott Joule (1818–1889), the English physicist who demonstrated the mechanical equivalent of heat.
Common contexts: physics, chemistry, engineering.
