This tool helps convert from uV (microvolt) to dBµV (deciBel microvolt)
Note that uV is a positive number that represents the root-mean-square voltage and it cannot be less than zero.
dBµV = 20*Log10(µV)
The dB scale is a very convenient representation for large numbers and allows for easy multiplication of two linear quantities. uV/m is used by the FCC to specify radiated limits for RF equipment. The first three columns of the following table of Radiated Emissions Limit is from .
|Freq. (MHz)||uV/m||dBuV/m||Distance (m)|
