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 2.5 knots into miles per hour we have to multiply 2.5 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

2.5 kt → V(mph)

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

V(mph) = 2.5 kt × 1.1507794480225 mph

V(mph) = 2.8769486200564 mph

The final result is:

2.5 kt → 2.8769486200564 mph

We conclude that 2.5 knots is equivalent to 2.8769486200564 miles per hour:
