Rowing Split Calculator

Rowing Split Calculator

Rowers and erg athletes measure effort as the split — the time to cover 500 metres — not minutes per kilometre. Enter the distance you rowed and how long it took, and this calculator returns your /500 m split, the equivalent power in watts and calories per hour using the Concept2 formulas, plus your speed in m/s and km/h. Use it to set interval targets, pace a 2 km test, or compare ergometer sessions on the same scale.

Rowers measure effort as the time it takes to row 500 m (the "split"). Power and calories use the Concept2 formulas (watts = 2.80 / pace³, where pace is seconds per metre). A 2:00/500 m split is a common fitness benchmark; sub-1:40 is competitive. Values assume a constant pace over the whole piece.
