Road/Track
It depends on the track size. Middle school tracks are commonly half the size of "normal" high school tracks. 800m is either 4 laps on a middle school size track or 2 laps on a high school size track. 1600m is either 8 or 4.
1600m 4 laps around a track each lap 400m
1600m is 1.6km
Traditionally in track and field, a one mile run is 1600m = 4 laps of a standard 400m track. A mile is actually about 1609m, but any mile events are rounded to 1600m. In that case, 1.5 miles would be 6 laps or 2400m.

Yes, Javelin is a sport. It is a track and field event.
While 1600m is closer to a true mile, there is no specific reason why internationally the 1500m is ran instead of the 1600m. The 1500m race started in the late 1800s in Europe, most likely as a metric version of the 1 mile race the Americans were running during that time. Once the metric system became the widely accepted measurement standard throughout most of the world the 1500m was officially adopted by International competition. With a record book spanning over 100 years for the 1500m race, it is unlikely the 1600m will become an official International race. The 1600m however, is most commonly ran in Highschool track.
