British mile is a unit of length equal to 5,280 feet or 1,760 yards (1,609 meters), used in the United States and other English-speaking countries. Also called land mile, statute mile.

Metric mile is an informal unit of distance used mostly in athletics. The metric mile is equal to 1500 meters or 1.5 kilometers (approximately 0.932 057 statute mile or 4921.26 feet). In U.S. high school competition the term is sometimes used for a race of 1600 meters (0.994 194 miles or 5249.34 feet)!!

A British mile is the measurement used on roads and a Metric mile is the measurement used in Athletics on a running track etc. It is slightly shorter.

One never heard of metric mile rather it is km 1 mile=1.6km(approx)

The british mile is a kilometer. It is art of the metric system. a mile is running 14 football field straight across. A kilometer is running9 football fields long.
Another answer.

The British mile is not a kilometer. A kilometer being a metric measurement is only 5/8th of a mile. There is no difference between an British and an American mile, both are 1760 yards. So, miles are the same, the confusion comes with with gallons. A british gallon is 4.5 litres and an American gallon is 3.8 litres

British Mile = Metric Mile

British mile =1760yards where as One Matric mile =1500yrds

1 british mile =1760yards where as one matric mile =1500yrds......and the british mile is generally used in sports/athelatic events where as matric mile for the general purpose of distance measurement......
