Where the factor comes from

The U.S. Track & Field and Cross Country Coaches Association (USTFCCCA) publishes standardized event conversion factors used by coaches and meet entry systems: “Take the competitor’s total time in seconds and multiply by the factor shown. Always round up the last digit of the final time.” The 1500m → 1600m factor is 1.0737.

1600m time = 1500m time (seconds) × 1.0737, rounded up
