eV to keV Converter

Enter eV:

eV (electron Volt) and keV (kilo electron Volt) are units of energy commonly used in physics, particularly in fields such as atomic physics, nuclear physics, and particle physics. A keV is a larger unit compared to eV and is used to express energy values in the range of thousands of electron volts.

Relationship Between eV and keV

1 keV (kilo electron Volt) is equal to $10^3$ eV (electron Volts), or:

$$1 \, \text{keV} = 1 \times 10^3 \, \text{eV}$$

Conversion Formula:

To convert eV to keV, use the following formula:

$$\text{keV} = \frac{\text{eV}}{10^3}$$

Example Calculation:

If you have 5,000 eV, you can convert it to keV as follows:

$$\text{keV} = \frac{5,000 \, \text{eV}}{10^3} = 5 \, \text{keV}$$

Why This Conversion is Useful:

This conversion is important in many areas of physics, where energy measurements in the range of hundreds to thousands of eV are frequently encountered. For instance, in X-ray and gamma-ray spectroscopy, energies of photons are often expressed in keV because the energies of X-rays and gamma-rays typically fall into the keV range, making it a convenient unit for such applications.
