Treadmill Incline Converter

Uses the ACSM running energy-cost equation to convert any treadmill speed and incline combination into the flat pace with the same oxygen cost, plus a full incline table for your speed. Handy for hill sessions indoors and for comparing treadmill workouts with outdoor runs.

Notes

  • A 1% incline is the common convention to compensate for the missing air resistance indoors at typical training speeds.
  • The ACSM equation is calibrated for steady submaximal running; very steep or very fast settings extrapolate.
  • Educational estimate for sport and training purposes, not professional coaching or medical advice.
