## Conversion formula

The conversion factor from knots to miles per hour is 1.1507794480225, which means that 1 knot is equal to 1.1507794480225 miles per hour:

1 kt = 1.1507794480225 mph

To convert 5.1 knots into miles per hour we have to multiply 5.1 by the conversion factor in order to get the velocity amount from knots to miles per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.1507794480225 mph

5.1 kt → V(mph)

Solve the above proportion to obtain the velocity V in miles per hour:

V(mph) = 5.1 kt × 1.1507794480225 mph

V(mph) = 5.868975184915 mph

The final result is:

5.1 kt → 5.868975184915 mph

We conclude that 5.1 knots is equivalent to 5.868975184915 miles per hour:

5.1 knots = 5.868975184915 miles per hour

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 mile per hour is equal to 0.17038749841204 × 5.1 knots.

Another way is saying that 5.1 knots is equal to 1 ÷ 0.17038749841204 miles per hour.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five point one knots is approximately five point eight six nine miles per hour:

5.1 kt ≅ 5.869 mph

An alternative is also that one mile per hour is approximately zero point one seven times five point one knots.
