The unit used to measure the energy of an electromagnetic wave is called a photon.
The international unit for energy (and work) is the joule.
Photons are the smallest particles of electromagnetic energy. They are the fundamental unit of light and carry electromagnetic radiation.

There is no such thing as a "unit of electromagnetic". There are several units related to electricity, electromagnetic waves, etc., depending on exactly what aspect you want to measure. For example, in the case of electricity, there are units for voltage, current, intensity, power, frequency, and others.
The unit of measurement for electromagnetic fields is typically the tesla (T) or gauss (G), depending on the strength of the field. Instruments used to measure electromagnetic fields include gaussmeters and magnetometers.
A kilocalorie is not a measure of weight. It is a measure of energy
