Often used in the cable TV industry and only valid in 75Ω systems If you suspect the last one, please email me with details of your browser so that I can fix the problem. Select the Impedance then enter any one of the other parameters below and the rest will be calculated automatically Sorry, this calculator needs JavascriptĮither your browser does not support Javascript, you have disabled it or there is a problem with my page. The power P (dBm) in dBm is equal to 10 times the base 10 logarithm of 1000 times the power P (W) in watts (W) divided by 1 watt (W). ![]() This calculator converts between watts, dBm, volts and dBmV. dBm to watts conversion calculator How to convert watts to dBm. S9 is already a very strong signal, but to describe larger signals, steps of 10 dB are used instead of 6 dB. This means that each time the voltage is halved (6 dB) the signal strength decreases by one point. Watts dBm Volts Converter Watts dBm Volts Converter S-points go from S1 to S9 and each S-point is defined as a 6 dB change in signal strength.
