It can be the power ratio. If you measure voltage or sound pressure it is not the power ratio.
You don't. They measure quite different things, so there is no standard conversion. Ampere is a unit of electrical current. Decibel (dB) is a measure of signal gain.
Decibel is no real unit, it is a pseudo unit. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity. A change in voltage ratio by a factor of two is approximately a 6 dB change. A change in power ratio by a factor of two is approximately a 3dB change.
There are two: the bel, or more commonly, the decibel, which is a logrithmic representation of the pressure of a sound, and the phon, which is a measure of how loud a sound is perceived.
A tenth of a bel. It's a ratio of two values of the same unit.
The unit for loudness is the decibel (dB). It is a logarithmic unit used to measure the intensity of sound.
Decibels are the measure of how loud something is.
decibels measure the intensity of sound.

pretty sure your looking for the decibel (db)
The decibel is a unit used to measure the intensity, or power, of a sound. It is a logarithmic unit that compares the power of a sound to a reference level. The decibel scale is commonly used to quantify sound levels and express changes in sound intensity.
The decibel (dB) is a unit of measurement used to express the intensity of a sound. It is a logarithmic scale that quantifies sound pressure levels in relation to a reference level. The decibel scale is commonly used to measure and compare the loudness of sounds.
Decibel (dB) is a unit of measurement for sound intensity or power level, while hertz (Hz) is a unit of frequency. They measure different aspects of sound and are not directly convertible to each other.
It can be the power ratio. If you measure voltage or sound pressure it is not the power ratio.
