Watts Calculator

If you’re interested in seeing how your erg pace converts to power (watts), this is the calculator for you.

Or, if you know your watts output and want to figure out what the equivalent pace would be, this is also the calculator to use. This Pace/Watts calculator can be used for all Concept2 RowErgs, the SkiErg and the BikeErg.

How to Use this Calculator

Enter your average pace per 500 meters to determine your power in Watts, or enter your Watts to determine your average pace per 500 meters.

Formulas Used

2.80 is a constant used in both formulas. The formulas used are:

  • watts = 2.80/pace³
  • pace = ³√(2.80/watts)

where pace is time in seconds over distance in meters.

For example: a 2:05/500m split = 125 seconds/500 meters or a 0.25 pace. Watts are then calculated as (2.80/0.25 ^ 3) or (2.80/0.015625), which equals 179.2.
