View Full Version : Pool distance question

July 29th, 2007, 08:29 AM
I was going to post this question in the 40 min. mile thread, but thought it might be too much of a diversion. But the mention of 1600 m. as a mile gave rise to my question. How does 1600 meters compare to, say, 1800 yards distance-wise? I've always used 1800 as my measure of a mile, since it wouldn't be too practical to stop 10 yards into the lap after 1760. ;)

I've also heard people refer to 1650 yards as a "pool mile." So now I have to admit I'm a little confused as to what in fact is universally accepted as a mile and what mile measure then applies to open water. I don't mind "erring" on the longer side, since if it's shorter than I think, I'll suddenly be faster! :D

1650 yards is the equivalent of 1500 meters, the international distance.

A mile is always going to be 1760 yards, 1600m is close to a mile. 1650 yards is the distance in yard that compares to a 1500m. 1800 yards is 40 yards longer than a mile.

Being in Canada we stiill have a few yards pools but we now have mostly meters pools. All new pools are meter pools. I am not sure but most pools in the USA are yards pools.

The school kids here do not know what yard, feet, inches or miles are, they are usuing the metric system of measurement.

The USA gallon is one fifth smaller than the imperial gallon which we no longer use in Canada we use litres when we fill our gas tanks and it takes 3.8 litres to make a US gallon and 4.5 litres to make a Canadian gallon.

According to my conversion program 1600 meters is .99 of a mile. A meter is roughly 39" so a yard and a meter are fairly comparable.

25 m is nearly 82.5 feet
50 m aprox 165 feet
100 m nearly 110 yards not quite.

A meter is very nearly 1.1 yard,so 1600M is nearly 1760 yd. as was noted.I have wondered why we do 1500M instead of 1600M as our longest pool race.Our progression is 100,200,400,800,1500. It makes even less sense in track as 4 laps is 1600M and their progression is 400(1 lap)800(2 laps) and 1500.

Allen the reason is there was really never meant to be a mile. It was invented by some brit.

Maybe his name was Foot. He was probably six feet tall, measured by the length of his foot. He divided the foot by twelve and found the segments and named them inches. He took a large step and found that it was three feet long. He then called that a yard. He stepped off the Canadian Foot Ball field and found out that it was a 110 large steps, that makes a football field in Canada is 110 yards long nearly 100mts long. He went to Bufallo and found out that the footbal field there is only 100 yards or 300 big steps.

Have a look here http://en.wikipedia.org/wiki/Foot_(unit_of_length)

Here's a little trick some of you might not know about: Google does unit conversions. Just type in "1800 yards to miles" and it will return that 1800 yards = 1.0227 miles. You could also ask what 1600 meters is in yards or miles. I use this feature all the time for various conversions.

How did we ever live without Google?

Thanks for the informative replies! All very helpful! So, basically either 1760 yds. or 1600m can almost equally be used as a mile measure. But do they use 1650 to measure open water miles or 1760?

The Brit who used his feet to measure distance might have had a problem when working with distance across water unless he could walk on water, but the only guy I know of who has that ability wasn't born in Britain, as I recall. :)

The mile in open water is 1760 yard or 5280 feet. That 1650 is a nothing measurement, it is used when trying to equate to 1500 meters. We used it in Olympic trials once that I know of in Canada.

Open water - 1 nautical mile = 2 025.37183 yards. I hate the nautical mile, the Cross on the hill in Port Alfred is 1 Nautical mile to the finish line. My boatman put up a sign it said sprint as I was infront of the cross. The tide was going out and the sprint took well over one hour.

maybe it all has to do with the length of the pool.
for the pool mile, 1500 is 30 lengths LCM, 60 lengths SCM.
a 1650y is 66 lengths. i guess someone thought doing 70 was 4 too many. or maybe they miscounted (novel idea) and just said "screw it, 1650 it is."

Well, I did 2600 easy (taper mode) today and darn, didn't think to check my time at 1650. 1800 was 43:39, not pushing hard at all, although occasionally picked up on a lap here and there. Getting closer to The Event! Excited.. nervous!
