MEASUREMENTS UNITS AND EQUIVALENCES

Description: 



how to use it:

  • find the units of the value to translate in the left column
  • and then use the corresponding formula under the units column desired.

example:

convert 15 dbm to dbmv for 75 ohms impedance.

procedure:

find in the row "dbm" the conversion formula for the column "dbmv",

which is: dbm + 30 + 20 log z ,

then :

dbmv = 15 + 30 + 20 log 75 = 40 + 18.75 = 58,75 dbmv (75 ohms)
