Sec. 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.

    (c) Graph 3. To convert received power in dBW to field intensity in 
dBu find the received power in dBW on the horizontal axis. Move 
vertically to the diagonal line, then move right horizontally to read 
dBu.
