A swim time converter translates competitive swimming race times between the three standard swimming pool course lengths: Short Course Yards (SCY, 25-yard pools used in US high schools and NCAA), Short Course Meters (SCM, 25-meter pools), and Long Course Meters (LCM, 50-meter Olympic-sized pools). It applies official NCAA and USA Swimming conversion factors based on stroke, turns, and distance.
T_{\text{LCM}} = (T_{\text{SCY}} \cdot F_{\text{course}}) + \Delta T_{\text{turns}}Because 1 meter = 1.09361 yards, 25m courses require ~1.11x the yard time, and 50m long course pools have fewer push-off turns, adding turning resistance.
Scenario: A male swimmer swims a 48.50-second 100-yard freestyle in SCY.
SCY time: 48.50 seconds.
SCM conversion factor (1.11): 48.50 × 1.11 = 53.83 seconds.
LCM conversion factor (fewer turns in 50m pool): ~55.29 seconds.
SCY is Short Course Yards (25 yards per lap). SCM is Short Course Meters (25 meters per lap). LCM is Long Course Meters (50 meters per lap, the Olympic pool standard).
A meter is approximately 9.36% longer than a yard, and a 50m pool has half as many flip turns and underwater wall pushoffs, where swimmers travel fastest.
Many high school and collegiate championship meets accept converted times using official NCAA or USA Swimming conversion tables when swimmers have not raced in a specific pool length.
You can enter seconds and hundredths (e.g. 48.50 or 23.12) or minutes, seconds, and hundredths (e.g. 01:02.35).
