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 0.5 knots into miles per hour we have to multiply 0.5 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

0.5 kt → V(mph)

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

V(mph) = 0.5 kt × 1.1507794480225 mph

V(mph) = 0.57538972401127 mph

The final result is:

0.5 kt → 0.57538972401127 mph

We conclude that 0.5 knots is equivalent to 0.57538972401127 miles per hour:

0.5 knots = 0.57538972401127 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 1.7379524838028 × 0.5 knots.

Another way is saying that 0.5 knots is equal to 1 ÷ 1.7379524838028 miles per hour.

Approximate result

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

0.5 kt ≅ 0.575 mph

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