Miles (mi) to Kilometers (km) Converter

This length unit converter dynamically calculates the value you enter in miles (mi) and converts it to its equivalent value in kilometers (km).

How many miles (mi) are in 1 kilometer (km)? What is the formula for how to convert miles to kilometers (mi to km)?

1 mile (mi) = 1.609344 kilometers (km)
So we can say that there is 1.609344 kilometers in 1 mile.
This means that the multiplication conversion factor to convert a quantity expressed in a mile unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 1.609344.

Inversely (or reciprocally),

1 kilometer (km) = 0.62137119223733 mile (mi)
So we can say that there is 0.62137119223733 mile in 1 kilometer.
This means that the division conversion factor to convert a quantity expressed in a mile unit of measurement to an equivalent quantity expressed in a kilometer unit of measurement is 0.62137119223733.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in miles to an equivalent quantity of length expressed in kilometers (mi to km). Both formulas will yield the same result. The formulas are:

km = mi ร— 1.609344 ย  ย โ†’ This is the formula based on the multiplication conversion factor.

and

km = mi รท 0.62137119223733 ย  ย โ†’ This is the formula based on the division conversion factor.

For example, if you have a length of 500 miles that you want to convert to kilometers, you would use either of the two formulas as follows:

km = 500 mi ร— 1.609344 = 804.672 km
km = 500 mi รท 0.62137119223733 = 804.672 km

So, the result is the same using either formula, which is 804.672 kilometers.
