1 mile = 1.609344 kilometers, which is what you need for speed conversions and reading maps.
How does a nautical mile differ from an ordinary mile?
A nautical mile is 1852 meters and is used in shipping and aviation, while a statute mile is 1609.344 meters. They are not the same.
Does the tool accept scientific notation?
