Treadmills

Q. Are there any charts that give Watt out put at level ramp and rpm settings for the treadmill?

Treadmills do not provide Watt readings but do provide MET readings. There is a formula to convert METS to Watts however that depends on body weight. Or you can compare calories per minute and Watts with this formula: 1 cpm = 69.77 Watts

RPM on a treadmill would equate to the number of strides per minute. You can measure the number of times that one foot plants per minute to determine stride rate.
