How to Convert uT to w/m2

[epsolutions]

Is there any way to make a mathematical conversion between watts per square meter to Teslas?

For example, if a 10mW/m2 RF signal was measured at a given surface, how can the magnetic component of the signal be quantified in micro Teslas?

not that I'm aware of as they are 2 totally different things
one is an EM field strength, the other is a magnetic field

Edit
looks like I may stand corrected ……..

uT = W/m² / 239 (Micro-Teslas = Watts per square metre divided by 239)

nT = W/m² / 239,000 (Nano-Teslas = Watts per square metre divided by 239,000)

I now recall seeing that 239 figure before. It is reflected in the attached chart where 960 W/m2 equals 1.0167 uT

But, as you say, a static magnetic field and an EM signal per surface area are two different phenomena. However, they seem to be subject to correlation somehow. Possibly because EMR has a magnetic vector that can be quantified?

However, I do not understand the "real life" significance.

Can someone please explain according to what physical laws can a force (magnetism) and a different force (EMR) per surface area at an unspecified frequency be equated? I have researched extensively online and can find no definitive answer.

because W/m² doesn't need to have a specific frequency

I believe frequency and wave form are related to signal density. That aside, what about the rest of my question?

no they are not
