VO2 Max Calculator
Estimate VO2 max with a Cooper 12-minute distance, a 1.5-mile time, or the maximum-to-resting-heart-rate ratio method.
Formula
Cooper: VO2 max = (distance m - 504.9) / 44.73; 1.5 mile: 3.5 + 483 / minutes; heart-rate ratio: 15.3 x max HR / resting HR.
About the VO2 Max Calculator
Estimate VO2 max with a Cooper 12-minute distance, a 1.5-mile time, or the maximum-to-resting-heart-rate ratio method.
How the VO2 Max Calculator Works
Only the equation selected in the method menu is applied, and its required field is validated before the estimate is returned in mL/kg/min.
Formula
Cooper: VO2 max = (distance m - 504.9) / 44.73; 1.5 mile: 3.5 + 483 / minutes; heart-rate ratio: 15.3 x max HR / resting HR.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
These are population equations, not a direct metabolic-cart measurement. Protocol, pacing, age, fitness, environment, medication, and heart-rate measurement can alter accuracy.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
