How to convert $$\ kWh/m^2$$ to $$\ Joule/kg$$
I want to compare the radiation produced by the sun over a location (where I live in, measured in $\ kWh/m^2$), to the radiation a person gets from a CT scan in the unit sieverts (Sv, whose equivalence is $\ Joule/kg $).
Thus you may want to know what produces more radiation: The Global Horizontal Sun Radiation over Vilnius versus the radiation produced by a regular nose CT scan (which is in Sieverts)
For instance, you may get the solar radiation over a location data from https://globalsolaratlas.info/?c=-28.56667,-70.75,3&s=-28.56667,-70.75 But I don't know how to compare both magnitudes
I need it for a research I am working on. Thank you.
These two units don't match up.
You have a density of energy in $kWh = \frac{1000}{3600} Joule$ per square meter.
And you have a mass density of energy in Joule.
So you can't convert from one to another unless you had more information.
Also, this is probably more appropriated in the physics SE.
