Just a practice set for those needing to get good at coverting between dBuV and mV in their head. Sure its one thing to perform the calculations using algebra, its another to be able to quickly estimate values in your head.
120 dBuV
1000 mV or 1 V
110 dBuV
~316.2 mV
100 dBuV
100 mV
90 dBuV
~31.62 mV
80 dBuV
10 mV
75.5 dBuV
~6mV
74 dBuV
~5 mV
72 dBuV
~4 mV
70 dBuV
~3.162 mV
66 dBuV
~2 mV
60 dBuV
1 mV
50 dBuV
~0.3162 mV
40 dBuV
0.1 mV
30 dBuV
~0.03162 mV
20 dBuV
0.01 mV
10 dBuV
~0.003162 mV
0 dBuV
0.001 mV
