What this calculator does

It converts units exactly, derives distance from speed and time, and applies the ACSM walking or running metabolic equation. Results are estimates for comparison, not readings from your treadmill or body.

Method references: the American College of Sports Medicine (ACSM), Guidelines for Exercise Testing and Prescription, 12th edition, Appendices C and D, the NIST unit conversion table, and a peer-reviewed walking-equation comparison.
