Rowing split calculator
This rowing split calculator turns your 500 m split into watts and shows times for 2000 m and other distances. A split of 2:05 is about 179 W.

How it is calculated
The split is the time the ergometer shows for 500 metres. A split of 2:00 means 4 minutes per kilometre and a power of about 202 watts; a split of 1:50 is about 263 watts.
How it is calculated
The machine maker calculates power as watts = 2.80 / pace³, where pace is the seconds per metre, that is the split divided by 500. Speed enters with the third power: 10 percent faster needs about 37 percent more power. The reverse is pace = (2.80 / watts) to the power of one third. From the split follows the time for any distance: split times distance divided by 500.
Which distances are common?
On the ergometer 2000 m is the standard distance for races and tests, together with 500 m, 1000 m, 5000 m, 6000 m and 10,000 m as well as the half marathon and marathon. With the mode “From distance and time” you get the split you rowed for it.
- The time per 100 m helps with intervals and short pieces.
- The speed in km/h allows comparison with other sports.
- For weight classes and comparisons, power per kilogram of body weight often matters as well.
Frequently asked questions
How do I convert a split to watts?
Watts = 2.80 divided by (split in seconds / 500) cubed. For 2:05 that is 125 / 500 = 0.25 and so 2.80 / 0.015625 = 179.2 W.
How long does 2000 m take at a 2:00 split?
Four times 500 m gives 4 × 2:00 = 8:00 minutes.
How many watts does a 1:45 split need?
About 302 W. Even a few seconds faster needs much more power because speed enters with the third power.
