73 eV = 0.073 keV

keV = eV × 0.001

Electronvolts to Kiloelectronvolts: 1 eV equals 0.001 keV. To convert electronvolts to kiloelectronvolts, multiply by 0.001 (keV = eV × 0.001). For example, 10 eV = 0.01 keV.

How to Convert Electronvolts to Kiloelectronvolts

To convert from electronvolts to kiloelectronvolts, multiply the value by 0.001. The conversion is linear, meaning doubling the input doubles the output.

Conversion Formula

  • Electronvolts to Kiloelectronvolts: keV = eV × 0.001
  • Kiloelectronvolts to Electronvolts: eV = keV ÷ 0.001

Understanding the Units

What is an Electronvolt?

An electronvolt equals approximately 1.602 × 10⁻¹⁹ joules — the kinetic energy gained by a single electron accelerated through a one-volt potential difference.

Common contexts: particle physics, atomic spectroscopy, semiconductor band gaps.

What is a Kiloelectronvolt?

A kiloelectronvolt equals 1,000 electronvolts (10³ eV).

Common contexts: X-ray energy, nuclear medicine.
