## 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 3.4 knots into miles per hour we have to multiply 3.4 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

3.4 kt → V(mph)

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

V(mph) = 3.4 kt × 1.1507794480225 mph

V(mph) = 3.9126501232767 mph

The final result is:

3.4 kt → 3.9126501232767 mph

We conclude that 3.4 knots is equivalent to 3.9126501232767 miles per hour:

3.4 knots = 3.9126501232767 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 0.25558124761806 × 3.4 knots.

Another way is saying that 3.4 knots is equal to 1 ÷ 0.25558124761806 miles per hour.

## Approximate result

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

3.4 kt ≅ 3.913 mph

An alternative is also that one mile per hour is approximately zero point two five six times three point four knots.
