They measur the miles of highway in use. Starting from the west at one mile amd from the south at one mile. SO if you were traveling from the western or southern border of your state you would know exactly how many miles you had come.
Added: The mile markers also PRIMARILY identify the location on the Interstates so that emergency and service vehicles can identify where they are. The intersections are few and usually far between and there are no intersection roads, so being able to pinpoint the location of an incident becomes of prime importance.
Mile Markers was created in 2005.
Yes, there are half mile markers
Mile markers on highways typically run from east to west to provide consistency in navigation and directions.

A square mile is a measure of area, such as the acreage of a plot of land. A mile is a measure of length or distance, such as from one city to another.
10560 feet = 2 miles = 10 two-tenths of a mile. Including the starting marker, you would require 11 markers on each side of the road.
mph is a measure of speed: miles per hour mile is a measure of distance; These are not comparable.
Mile marker #1 is 1 mile N. of the Southern border of the state. Not sure how east west works. For West to East, mile marker #1 is 1 mile east of the western border of the state
An acre is a measure of area, a mile is a measure of distance, so your question cannot be answered.
A 'quart' is a unit used to measure volume, and a 'mile' is a unit used to measure distance. Since they are two completely different things, you cannot measure quarts in a mile, or vice versa.
