-6 dB to gain +3 dB to power 2x gain to dB 4x power to dB

Result

6.02 dB

A power ratio of 4x equals 6.02 dB.

Decibels 6.02 dB

Input ratio 4x

Equivalent amplitude ratio 2x

Formula 10 * log10(power ratio)

How to use this tool well

Use amplitude mode for level/gain moves and power mode for energy or intensity comparisons.
The formulas differ, so keep an eye on whether the source system is speaking in gain or power terms.

Quick examples

-6 dB -> 0.501187x gain
2x linear gain -> 6.02 dB
-3 dB power -> 0.501187x ratio
