dB to Volt Calculator
What is dB to Volt Conversion?
A dB is a unit of measure used in the log of two quantities; it measures gain or loss and power levels in electronic systems. As a measure of voltage level to reference voltage level, dB finds several applications in audio or electrical engineering. Often, in this context, the dB measured needs to be converted to volts for the evaluation of the strength of signal, volume, or transmission power in most applications of electronic and sound systems.
dB to Volt Conversion
dBV to Volts
dBV is a unit representing voltage in decibels relative to 1 volt (V). Converting dBV to volts tells you the actual voltage level based on the following formula:
\[ V = 10^{\frac{\text{dBV}}{20}} \]
Where \( V \) is the voltage in volts.
dBm to Volts
dBm represents power in decibels relative to 1 milliwatt (mW). When converting dBm to volts, the impedance (typically measured in ohms) of the circuit is required. The formula for conversion is:
\[ V = \sqrt{10^{\frac{\text{dBm} - 30}{10}} \times R} \]
Where:
- \( V \) = Voltage in volts
- \( \text{dBm} \) = Power in decibels relative to 1 mW
- \( R \) = Impedance in ohms (Ω)
What is a dB to Volt Calculator?
An easy-to-use dB to Volt Calculator enables engineers, audio specialists, and others working with electronic signals the conversion of decibel (dB) values into voltage (V) values. When a value in dB has been entered or entered along with impedance to be used, it is easy to compute the corresponding voltage. The application is very useful in audio setups, radio frequency engineering and power measurements where precise voltage levels have to be determined from dB values.
