300m Hurdles to 400m Hurdles Conversion (Girls)

High school and college race different distances or hurdle heights, so college standards need a conversion: men ×1.41, women ×1.45 (same hurdle height in high school and college). These are standard coaching conversions, a close estimate rather than an exact race result. The standards search on this site applies them automatically.
