  § 80.761   Conversion graphs.

   The following graphs must be employed where conversion from one to the
   other of the indicated types of units is required.

   (a) Graph 1. To convert effective radiated power in watts to dBk or to
   dBW, find the power in watts on the horizontal axis. Move vertically
   along the line representing the power to the diagonal line. Move
   horizontally from the diagonal to the right side to read dBW and to the
   left to read dBk.

   (b) Graph 2. To convert microvolts across 50 ohms to received power in
   dBW, find the signal in microvolts on the horizontal axis. Move
   vertically to the diagonal line, then move right horizontally to read
   dBW.
