This tool converts deciBel (dB) to its equivalent Absolute Value.
Formula
To convert decibels (dB) to its equivalent Absolute Value, you can use the following formulas depending on whether you are dealing with power or amplitude:
For Power
When converting dB to a power ratio, use the formula:
Absolute Value (Power Ratio)=10(dB/10)
For Amplitude
When converting dB to an amplitude ratio, use the formula:
Absolute Value (Amplitude Ratio)=10(dB/20)
The Absolute Value is always a Positive Number
Example Calculations
- 10 dB converts to Absolute Values of Power Ratio = 10 and an Amplitude Ratio = 3.16
- -10 dB converts to Absolute Values of Power Ratio = 0.1 and an Amplitude Ratio = 0.32
