Time conversions

Um, I swim 25m in 17.5sec, and 50m in 39.0 sec, currently. (Both pushing off.) Quite a diff in pace innit? :) I suspect that the WR for SC is 9.5ish, and 20.26. (Both dive-ins.) Therefore, I believe that your 50m time is around 2.15x your 25m time, based on my current Newbie status, and the WR status (of which 9.5sec is admittedly an "educated" estimate, based on what I see in the 20.26 video.) I could be wrong. :) So I did a bit of a calculation, I got the ratios for this year's men's and women's NCAA championships for the 50 free. Averaged 2.077 for men and 2.068 for women. However... this wouldn't really be a straight 50 to 25 conversion because you don't hit the pad until the end of the flip turn at the 25 mark of the 50. It also wouldn't work for other strokes - backstroke would be closer to 2 because the start is not as much of an advantage as the dive. Breaststroke would be much greater than that because it is a slower stroke so the advantage from the dive is much more. Fly would be in between free and ***. And then you have to consider that the athletes swimming the finals of the 50 at NCAAs are very, very good at starts, while many Masters level swimmers are... not. So that's another variable. Lots of caveats there.

www.swimmingworldmagazine.com/time-conversion That is a good site, but does not have the option of 25's. 50 is the lowest distance.

Since 25s aren't official events they aren't swum very often, so I wouldn't expect most people to have a real accurate seed time. Dividing by two will be close enough. Ok, thank you and once again thanks for all the feedback!

Well said. This was going to be my solution, too! Well, yes, obviously I did think of that but felt it would not be accurate enough - would you divide your 100 time by 2 to get a 50? Anyway, I really do appreciate all the feedback. This is the first time I have posted though have been reading and learning a great deal from the posts for a long time now and thought that maybe the experienced minds on here would have a solution for me! So I guess I will just go ahead and divide by two! Thanks again!

Are you asking to covert a long course meters time to a short course meters time? Or to somehow convert a 50m race to a 25m race? A 50 m race to a 25 m race, from either LCM or SCM. I need it for a seed time and have not swum 25's in meets yet.

Divide by 2. Done. Well said. This was going to be my solution, too!

There really is no formulaic conversion for that. Either just estimate something, or get somebody to time you in practice. Seed times don't mean a ton in local Masters meets anyway.
