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

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

Inversely (or reciprocally),

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

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 kilometers to an equivalent quantity of length expressed in miles (km to mi). Both formulas will yield the same result. The formulas are:

mi = km × 0.62137119223733    → This is the formula based on the multiplication conversion factor.

and

mi = km ÷ 1.609344    → This is the formula based on the division conversion factor.

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

mi = 500 km × 0.62137119223733 = 310.68559611866 mi
mi = 500 km ÷ 1.609344 = 310.68559611866 mi

So, the result is the same using either formula, which is 310.68559611866 miles.
