# RTL-SDR units, $\textrm{dBm}$

I am using the Python rtlsdr library to get complex samples from my RTL-SDR USB stick. I am getting power by squaring the real and imaginary components of these values, and adding them.

• What unit is the result in?
• If not $\textrm{dBm}$, how can I get to $\textrm{dBm}$?
