This efficiency reference table shows the efficiency for a range of useful output values, assuming a total input of 100. Every figure is computed with the same engine that powers our Efficiency Calculator, so the numbers are exact.
| Useful output | Efficiency | Energy lost |
|---|---|---|
| 20 | 20.00% | 80.00 |
| 40 | 40.00% | 60.00 |
| 60 | 60.00% | 40.00 |
| 80 | 80.00% | 20.00 |
| 120 | 120.00% | -20.00 |
| 160 | 160.00% | -60.00 |
| 240 | 240.00% | -140.00 |
| 400 | 400.00% | -300.00 |
| 560 | 560.00% | -460.00 |
| 800 | 800.00% | -700.00 |
How to use this table
Find the row closest to your useful output and read across to the efficiency. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Efficiency Calculator for a precise answer.
Need a value that is not in the table? — the Efficiency Calculator does it instantly, for free, with the formula and a worked example built in.
