Converting watts to avg/500m

Hi everyone,

I read a couple of essays about training on the erg, which said that there was a formula to convert watts into an avg/500m time. Unfortunately the formula was never stated so I wonder if any of you could help me.

kindly, Samson

Power = 2.8 * velocity^3

velocity is in meters per second so divide 500 by the pace, cube it, then multiply by 2.8.

All the maths you'll ever need for the ergo is documented at: http://www.atm.ox.ac.uk/rowing/physics/ergometer.html

Thank you very much. Citroen's link almost stroke me to death but I seem to have gotten the idea now.

The website for the lazy ones is just perfect for me...
