EMF/EMR units conversion



So many types and units?

One of the reasons for the confusion around Electromagnetic non ionizing radiation must be the many types of it and the different units in which we measure each and every type of EMR.


ELF types and units

Eextrem Low Frequency EMR has 2 types of fields: Electric and Magnetic fields.
The electric filed is usually left a side unattended, but the units are Volt per meter (V/m).
The magnetic fields has 2 units: milli Gouse(mG) and microTesla(UT)
The conversion between the 2 is very simple:
10mG=1uT


RF types and units

When referring to Radio Frequency (High Frequency) Electromagnetic non ionizing radiation there are 2 types of fields: Electric and Magnetic fields. This time the Magnetic field is usually left out. The Electric field is measured in units of Volt per meter (V/m). 
When measuring RF radiation you usually measure the Electric field or The power density. The power density is measured in units of mW/m2 or uW/cm2.
 

Conversion from Electric Field to RF power density

It is possible to convert between the Electric field and the power density, but only in the far field.
In the following formulas S is the electromagnetic radiation power density and V is the electric field strength. 
In order to convert from electric field (marked as V, units are Volt per meter) to units of electromagnetic radiation power density(marked in S), in units of micro Watts per square Centimeters, you need to use the following formula:
                


In order to convert from electric field (marked as V, units are volt to meter)to units of electromagnetic radiation power density(marked in S), in units of mWatts per square meter, you need to use the following formula:
