How to convert joules to kilo electron volts (J to keV)

The formula for converting joules to kilo electron volts is: keV = J × 6241509074461000. To calculate the joule value in kilo electron volts first substitute the joule value into the preceding formula, and then perform the calculation. If we wanted to calculate 1 joule in kilo electron volts we follow these steps:

keV = J × 6241509074461000

keV = 1 × 6241509074461000

keV = 6241509074461000

In other words, 1 joule is equal to 6241509074461000 kilo electron volts.

Example Conversion

Let's take a look at an example. The step-by-step process to convert 9 joules to kilo electron volts is:

  1. Understand the conversion formula: keV = J × 6241509074461000
  2. Substitute the required value. In this case we substitute 9 for J so the formula becomes: keV = 9 × 6241509074461000
  3. Calculate the result using the provided values. In our example the result is: 9 × 6241509074461000 = 5.6173581670149e+16 keV

In summary, 9 joules is equal to 5.6173581670149e+16 kilo electron volts.

Converting kilo electron volts to joules

In order to convert the other way around i.e. kilo electron volts to joules, you would use the following formula: J = keV × 1.602176487e-16. To convert kilo electron volts to joules first substitute the kilo electron volt value into the above formula, and then execute the calculation. If we wanted to calculate 1 kilo electron volt in joules we follow these steps:

J = keV × 1.602176487e-16

J = 1 × 1.602176487e-16

J = 0.0000000000000001602176487

Or in other words, 1 kilo electron volt is equal to 0.0000000000000001602176487 joules.

Conversion Unit Definitions

What is a Joule?

A joule (J) is the standard unit of energy in the International System of Units (SI). It is defined as the amount of work done when a force of one newton is applied over a distance of one meter in the direction of the force. In other words, one joule is equal to the energy transferred when one watt of power is dissipated for one second.
Mathematically, 1 joule is equal to 1 N × 1 m, or 1 kg × m2/s2 in terms of mass, length, and time.
Joules are a versatile unit of measurement used not only in physics but also in various fields including engineering, chemistry, and biology to quantify energy, work, and heat. For example, it's commonly used to express the energy content of foods, the capacity of batteries, and the energy output of electronic devices.

What is a Kilo Electron Volt?

A kilo electron volt (keV) is a unit of energy commonly used in the field of atomic and particle physics. It is equal to one thousand electron volts (eV). Like the electron volt, the kilo electron volt is primarily used to measure energies at the atomic and molecular scale.
Mathematically, 1 kilo electron volt is equal to 1,000 electron volts or 1 × 10 3 eV. It is often used to describe the energy of X-ray photons, gamma rays, and other subatomic particles. For example, X-rays used in medical imaging typically have energies in the range of 20−150 keV.
The prefix "kilo-" indicates a factor of one thousand, so a kilo electron volt represents a thousand times more energy than a single electron volt.
