Is there a basic rule thumb for converting 1500 times to mile times, and vice versa?

There's no rule.
Personally, I add 19 seconds to my 1500 PB.

1500 time x 1.08 = mile time
this is the generally accepted conversion
the easiest way is to convert to seconds then multiply
so, for a 4:00 1500... (4 x 60) x 1.08 = 259.2 = 4:19.2
So, yeah, 19 seconds works for a fairly competitive college runner.
However, if you ar a 5 minute miler... 300/1.08 = 277.8 or 4:37.8 for a differential of over 22 seconds.
and, of course faster miles get a smaller differential than 19 seconds
1500m time multiplied by 1.08
Or divide a mile time by 1.08 to get a 1500m equivalent.
The ratio if you maintained speed is 1.0727
1.08 accounts for having to slow down a bit to maintain pace another 109 meters.
This ratio works out for most of the top milers.
El G 1.083
Ngeny 1.073 (great mile race)
Morceli 1.082
Cram 1.080
Komen 1.081
The ratio is above 1.08 for most because the 1500m is run a lot more often and comparable efforts are not usually given in both events.
3:42.1 1500 converts to a 3:59.9 mile
This ratio has been used by USATF and NCAA for qualifying purposes.
