1600 to 1500 conversion 5/29/2007 9:36AM Reply | Return to Index | Report Post
I'm having trouble finding a conversion chart for a 1600 meter time to a 1500 meter time. Can anybody help?

Multiply by 15/16 to get pace equivalent.

Then take a second or two off to account for slightly shorter distance.

I added the product of the 1600m time and 15/16 with the product of the 1600m time and .002. The added time is certainly up for debate, but 100m is not going to affect the pace all that much so these numbers should be close. You should learn how to use a spreadsheet for basic things like this because it can be pretty handy and it's really not difficult at all.

Dammit I'm stupid, let me subtract that extra time instead of adding it.

Here's a corrected version.

i thought 342 was about a 4 minute mile? your chart has 344 as 400 for 1600 which makes 343 400 for a mile??

The IAAF scoring tables put a 4:00.01 mile at 3:42.40 for 1500m. So, like I said, you could adjust the .002 multiplier just a bit either way but it's never going to be exact.
no...

his chart has a 344 1500 as about a 4:00 1600.. about a 4:01.6 mile

not a chart, but this will take care of the conversion:

http://www.cs.uml.edu/~phoffman/ex1old.html

put in 1500m and your time, then voila! The middle column (purdy best) is generally the best estimate.

With any 1500 to 1600/mile conversion, its important to take into account how the race went. If your last 200-300 meters was faster than your average pace, what you would have run for the mile that day (as opposed to your mile equivalent) will likely be faster than tables/calculators tell you. Likewise, if your last 200m was a crawl, you probably wouldn't have run as fast as tables say for a full mile.

Most people call 3:42.2 = 4:00.0(mile). The IAAF charts say it's 3:42.4 (A). Since a mile is 1.0058 longer than 1600, I'd multiply the nominal 1600 time (column D) by 1.0058 to get a mile equivalent (C), then go to the charts to get a 1500 equivalent (E).

Here's a simple way to do the conversion that is probably more accurate. Divide the time of the slowest 400 you ran during the race by 4. Subtract that from your 1600 time (or add it to your 1500 time).

That's pretty clever, thanks.
Remember, if you ran a mile (or want to convert to a mile) rather than a 1600, you need to account for the slight difference in distance.
