Split Time to Watts Converter
The split time to watts converter translates your rowing ergometer pace into mechanical power output using the official Concept2 formula. On a Concept2 RowErg, split time (the time to cover 500 metres) and watts share a cubic relationship: Watts = 2.80 / pace³, where pace is expressed in seconds per metre. This means small improvements in split time require disproportionately more power. For example, a 2:00.0/500m split equals approximately 203 watts, while a 1:50.0/500m split equals approximately 262 watts — a 10-second pace improvement demands roughly 29% more power.

How This Works
Enter your 500m split time in minutes and seconds. The calculator converts your split to seconds per metre by dividing the total seconds by 500, then applies the Concept2 formula: Watts = 2.80 / (seconds per metre)³. The result is your mechanical power output in watts. This is the same calculation used internally by every Concept2 PM5 monitor to display wattage on screen. Because the relationship is cubic, the converter also shows you how much additional power is needed per second of split improvement at your current pace.
Formula
Watts = 2.80 / pace³, where pace = split_seconds / 500 (in seconds per metre)
