Yard ↔ Meter Pool Converter
Convert an event distance and time between short-course yards, short-course meters, and long-course meters — exact on distance, pace-equivalent on time.
Yards, meters, and the pool you race in
Swimmers who train in yards and race in meters — or move between a short-course winter and a long-course summer — constantly need to translate between courses. The distance side is exact: a yard is 0.9144 metres, full stop. The time side is where it gets interesting, because the same fitness produces different clock times depending on how many walls you get to push off. This converter is honest about that: it gives you the exact distance and a pace-equivalent time, and tells you which way reality will lean.
Combine it with the Swim Pace Calculator to see your per-100 in either unit, and the Distance & Lap Counter to convert whole-session volume.
Frequently Asked Questions
What are SCY, SCM, and LCM?
They are the three racing course types. SCY is short course yards, raced in a 25 yard pool and used across most of the United States. SCM is short course meters, a 25 metre pool used in winter racing in much of the world. LCM is long course meters, the 50 metre Olympic pool. The pool length and its unit change both the distance you swim and how many turns you get.
How do you convert a distance between yards and meters?
With the exact conversion factor: one yard is 0.9144 metres. So a 100 yard swim is 91.44 metres, and 100 metres is about 109.4 yards. Distance conversion is precise and has no assumptions — it is pure unit arithmetic, which the tool does in both directions.
How reliable is the time conversion?
It is a pace-equivalent estimate, not a race prediction. The tool holds your seconds-per-metre steady and scales by the physical distance, so a yard time becomes the metre time you would swim at exactly the same speed. Real times differ because meters courses are longer per length and long course has half the turns of short course — and turns are fast. Treat a converted meters time as a best case and expect to be a little slower.
Why is a long-course time usually slower than short course?
Turns and the underwater push-off that follows are among the fastest parts of a race. A 100 in a 25 m pool has three turns; the same 100 in a 50 m pool has only one. Fewer turns means more time spent swimming on the surface, which is slower than gliding off a wall — so long-course times run a bit behind short-course times for the same swimmer. This tool does not model that gap; it converts on pace alone.
Distance uses the exact 1 yard = 0.9144 m factor. Time is a pace-equivalent estimate that ignores turn count, so it is not an official course-conversion time.
