Rowing Split Calculator

Turn an average 500 m split into a total time for any distance, or a finish time into the split that produced it.

metres; 2,000 m is the standard test
the other one is calculated
m:ss or h:mm:ss, or plain seconds — e.g. 7:00, 1:02:03.4, 420
strokes per minute; adds stroke count and metres per stroke
Enter a distance and a time to see the split.

Rowing pace is quoted as the average time per 500 m, so the split is the elapsed time multiplied by 500 and divided by the distance in metres, and the total time is the split multiplied by the distance divided by 500. A 2,000 m piece in 7:00 is therefore 1:45.0 per 500 m, and that pace held for 5,000 m is 17:30.0. Speeds are simple distance over time, and the stroke figures assume the rate you enter held for the whole piece: strokes are the rate multiplied by the elapsed minutes, with metres per stroke dividing the distance by that count. Times are shown to the nearest tenth of a second and every figure is an average for the whole distance — starting effort, sprint finishes, current, wind and boat class are not modelled, and nothing is timed or measured.
