How do you calculate db?

Formula used: dB = 20 log10 ( Voltage 1 / Voltage 2 ) 1 Bel = 10 decibels (dB) Decibel The decibel (dB) is a unitless measurement for expressing ratios.

How do you convert db to dbm?

The unit dBm denotes an absolute power level measured in decibels and referenced to 1 milliwatt (mW). To convert from absolute power "P" (in watts) to dBm, use the formula dBm = 10*log (P/1 mW). This equation looks almost the same as that for the dB. However, now the power level "P" has been referenced to 1 mW.

How many volts in db?

dBu is a voltage standard where "zero" (as in zero dB on your meters) is considered to be. 0.775 volts and +4 dBu is therefore 1.23 volts. dBm is a power measurement (the "m" stands. for milliwatts), where +4 also happens to be 1.23 volts if the load impedance is 600 ohms.

How many dbm is 1 watt?

1 watt is equal to 30dBm: Convert decibel-milliwatts to milliwatts, watts, decibel-watts. Enter the power in one of the text boxes and press the Convert button: How to convert power in milliwatts (mW) to dBm. The power in dBm is equal to the base 10 logarithm of the power in milliwatts (mW):
