Estimate a 2K erg time from a 6000-meter test, a 60-minute test, or a custom reference result with a transparent power relationship.
How the 2K Erg Projection Works
The calculator converts the reference result to average watts, divides that power by an explicit reference-to-2K power ratio, and converts the resulting 2K watts back to a 500-meter split. Four splits produce the predicted 2K time.
| Reference test | Power relationship used | How to interpret it |
|---|---|---|
| 6000 m | Reference watts = 85% of 2K watts | World Rowing-reported elite benchmark |
| 60 minutes | Reference watts = 76% of 2K watts | World Rowing-reported elite benchmark |
| 500 m, 30 minutes, or another test | User-entered percentage | Use personal or team test history |
Why 500 m and 30-minute tests are custom
A short sprint emphasizes anaerobic power, while a 30-minute piece emphasizes sustained aerobic work. There is no single percentage that translates either result accurately for every rower, so the calculator does not invent one.
Reading the prediction
The output is most useful as a planning estimate and as a repeatable comparison when the same test and percentage are used. Recent test conditions, pacing, fatigue, and training profile can move the actual 2K result.
