About this converter
World Aquatics long course records read here in total seconds. Men run 100 free 46.40, 200 free 102.00, 400 free 219.96, 800 free 452.12, 100 back 51.60, 100 breast 56.88, 100 fly 49.45, 200 fly 110.34 and 400 medley 242.50. Women run 200 free 112.23, 400 free 234.18, 1500 free 920.48, 100 back 57.13 and 400 medley 263.65. One Ledecky 1500 equals nearly twenty Pan 100s. Rome 2009 marks from Biedermann and Zhang Lin survive from the super suit era before the 2010 textile rule. Paris 2024 and 2025 trials marks anchor the modern end.
How to use it
Pick two records and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try 1 Ledecky 1500 against Pan 100s to see how many sprints one distance queen spans.
Short course 25 m marks stay out because long course 50 m pools swim slower turns. Minute marks convert to seconds with the split noted per row. Volatile 2026 sprint marks were left out to keep confident numbers. Mixed and single sex relays stay out so individual records compare cleanly.
