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).
i thought 342 was about a 4 minute mile? your chart has 344 as 400 for 1600 which makes 343 400 for a mile??
That's pretty clever, thanks.
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).
