Refer to this post in my blog for an explanation of what the calculator is all about!
The calculator shows you equivalent rowing intensities expressed as pace (minutes & seconds/500m), as power supplied at the handle (Watts) and as rate of energy expended by the rower (Cal/hr). You can enter an intensity directly using one of these units or find the average intensity based on the distance and time of a row.
Optionally, you can also predict the total time, distance or Calories accrued when rowing at that intensity by entering one of these quantities.
You MUST use a colon (:) to separate hours, minutes and seconds.
