| De : | Vers : | Formule sous 50 Ohm: |
| dBµV | dBµA | dBµA = dBµV - 34 |
| dBµA | dBµV | dBµV = dBµA + 34 |
| dBµA | dBm | dBm = dBµA - 73 |
| dBm | dBµA | dBµA = dBµA + 73 |
| dBµV | dBm | dBm = dBµV - 107 |
| dBm | dBµV | dBµV = dBm + 107 |
| De : | Vers : | Formule sous "Z" Ohm: |
| dBµV | dBµA | dBµA = dBµV - 20 log (Z) |
| dBµA | dBµV | dBµV = dBµA + 20 log (Z) |
| dBµA | dBm | dBm = dBµA - 10 log (Z) - 90 |
| dBm | dBµA | dBµA = dBµA + 10 log (Z) - 90 |
| dBµV | dBm | dBm = dBµV - 10 log (Z) + 90 |
| dBm | dBµV | dBµV = dBm + 10 log (Z) + 90 |
