How to convert kilometers to miles?
Any physical quantity can be written as:
Q = nu , where n= numerical value and u = unit used
We know that:
1 km = 0.621371 mi
1 mi = 1.60934 km
So, you can easily convert your quantity in km to miles by simply multiply it by 0.621371
Hence, general formula to convert km to miles:
p(mi) = 0.621371 × p(km), where p is the numerical value
For example:
Convert 8 km to miles
8 km = 8 × 0.621371 mi = 4.97097 mi

Uses: Kilometre is the larger unit of length is used to measure the lenght of roads , height of big buildings etc. It is also used in various fields like physics, chemistry , medicines, mathematics etc for large measurements.
Countries that use km: Kilometre is the metric unit of length, so it is used by all other countries around the world except the US, Liberia and Myanmar.
About Mile (mi)
Name of unit: Mile
Abbreviation: mi
Unit system: Imperial System
