sensitivity units

I am working on FM receiver IC and I have some questions about sensitivity
I saw different datasheets and they mentioned differently in sensitivity.

Basically, I can see several of them in the following
(1) dbm
(2) dbuVEMF
(3) uVEMF

Can anyone tell me what is uVEMF and how can I convert it back to dBm as I need this value to calculate the system NF

Here I am trying to answer my question after detailed searching

V emf is the RF input voltage where it's referred to open terminal. I got the answer from a book " Secrets of RF circuit design". To be honest, only this book I can search to explain clearly the meaning of V emf

I think, you'll find an explanation in any profound RF text book. But one correct explanation should be sufficiant for the time being.

For FM receivers, the sensivity is measured as dBm for a certain SNR at the output.For instance, it's said -80dBm for 14dB SND etc.
