In a low-energy nuclear scattering experiment, it is conventional to refer to the nuclear recoil energy in units of eVr, keVr, etc. This distinguishes the nuclear recoil energy from the "electron equivalent" recoil energy (eVee, keVee, etc.) measured by scintillation light. For example, the yield of a phototube is measured in phe/keVee (photoelectrons per keV electron-equivalent energy). The relationship between eV, eVr, and eVee depends on the medium the scattering takes place in, and must be established empirically for each material.

Really, there are many specific websites that related to such online conversion(s).
Recommended dear Dr. Dibakar Pal.

Dear Debakar and Emad
Thank for your reply
we need the conversion of keV into keVee (keVee=kilo electron Volt electron equivalent)
not Kelvin to keV
Dear Durairaj,
I think we have to focus on 'electron-energy equivalent'. I could find only very little in the internet about this concept. These informations were poor altogether.
May be someone is able to explain that concept clearly.
In which context do you need such a conversion? (keV to keVee).
Dear professor
Thank you for reply
I am working on scintillation counting by neutron like particles scattering with medium.
A weakly interacting/neutral particle (e.g. neutron) can scatter off from the nucleus of your detector material and set the nucleus to recoil. The energy which the nucleus gains from the incident particle that sets it to recoil is measured in keVr. The recoiling nucleus can induce ionization (free electrons) in the detector which are recorded with different detector charge readouts. This fraction of the energy (in keVr) that causes ionization are measured in keVee. Hence, keVr and keVee are nuclear recoil and electron recoil energies, respectively. Mathematically, keVee = qn*keVr. where qn is the nuclear quenching factor of the detector material.
Dear Anthony Ezeribe,
Thank your reply,
is there any book or reference to know more details?
Hi Durairaj,
Radiation detection and measurement by G. F. Knoll and Particle Detectors by C. Grupen and B. Shwartz can be a good place to start. Also, you may want to read this (https://arxiv.org/pdf/1111.3260.pdf) paper.
Cheers.
