USTFCCCA standardized conversion factors
The U.S. Track & Field and Cross Country Coaches Association publishes one factor per pair of events — the same for men and women for every conversion on this page: “Take the competitor’s total time in seconds and multiply by the factor shown. Always round up the last digit of the final time.”

Why 1500 → mile is × 1.08, not just the extra distance
The mile is 109.34 m longer than 1500 m — about 7.3 % further. The factor is 8 % because you also have to hold the pace for longer, so the converted time includes a little extra slowdown. By contrast, 1600 m → mile (× 1.0058) covers only 9.34 m and almost no extra fatigue.
