This decibel gain reference table shows the gain for a range of input power values, assuming an output power of 100 W. Every figure is computed with the same engine that powers our Decibel Gain Calculator, so the numbers are exact.
| Input power | Gain |
|---|---|
| 0.25 W | 26.0206 |
| 0.5 W | 23.0103 |
| 0.75 W | 21.2494 |
| 1 W | 20.0000 |
| 1.5 W | 18.2391 |
| 2 W | 16.9897 |
| 3 W | 15.2288 |
| 5 W | 13.0103 |
| 7 W | 11.5490 |
| 10 W | 10.0000 |
How to use this table
Find the row closest to your input power and read across to the gain. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Decibel Gain Calculator for a precise answer.
Need a value that is not in the table? — the Decibel Gain Calculator does it instantly, for free, with the formula and a worked example built in.
