Power Output vs Split per 500m (min)
How Rowing Power Is Calculated
The Concept2 Formula
Watts = 2.80 / pace^3
Where pace = split time in seconds / 500 (seconds per meter).
Power-to-Weight
Watts per kilogram (W/kg) is a useful metric for comparing rowers of different sizes. Lightweight rowers may produce fewer absolute watts but can be very competitive on a W/kg basis.

Example Calculation
Calculate watts for a 1:55 per 500m split at 180 lbs body weight.
- 01Split in seconds = 1 x 60 + 55 = 115 seconds per 500m.
- 02Pace per meter = 115 / 500 = 0.23 sec/m.
- 03Watts = 2.80 / (0.23)^3 = 2.80 / 0.01217 = 230 W.
- 04Body weight = 180 x 0.4536 = 81.6 kg.
- 05Watts/kg = 230 / 81.6 = 2.82 W/kg.
