Officially a quarter mile, however, some tracks have shortened to an eighth mile for safety, and fuel consumtion reasons. All your NHRA major events will be a quarter mile though.
All NHRA certified strips are 1320 feet in length. After the death of Scott Kalitta the NHRA restricted Top Fuel Dragsters and Funny Cars to 1000 feet in an attempt to slow them down and provide for a longer shutdown area.

The length and width of the track is rather important - -
On a 400m track, each straight length is 100m, as well as each curve is 100m, totaling 400.
No, not according to the NHRA rule book.
400m
A length, at Churchill Downs or anywhere, is approximately eight feet.
The number of laps in 800 meters depends on the length of the track. For a standard outdoor track, which is 400 meters in circumference, 800 meters would equal 2 laps. If the track is a different length, you would divide 800 by the track's circumference to determine the number of laps.
