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

1 nautical mile (nmi) = 1.1507794480235 miles (mi)
So we can say that there is 1.1507794480235 miles in 1 nautical mile.
This means that the multiplication conversion factor to convert a quantity expressed in a nautical mile unit of measurement to an equivalent quantity expressed in a mile unit of measurement is 1.1507794480235.

Inversely (or reciprocally),

1 mile (mi) = 0.86897624190065 nautical mile (nmi)
So we can say that there is 0.86897624190065 nautical mile in 1 mile.
This means that the division conversion factor to convert a quantity expressed in a nautical mile unit of measurement to an equivalent quantity expressed in a mile unit of measurement is 0.86897624190065.

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

mi = nmi × 1.1507794480235    → This is the formula based on the multiplication conversion factor.

and

mi = nmi ÷ 0.86897624190065    → This is the formula based on the division conversion factor.

For example, if you have a length of 300 nautical miles that you want to convert to miles, you would use either of the two formulas as follows:

mi = 300 nmi × 1.1507794480235 = 345.233834407 mi
mi = 300 nmi ÷ 0.86897624190065 = 345.233834407 mi

So, the result is the same using either formula, which is 345.233834407 miles.
