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 2.1 knots into miles per hour we have to multiply 2.1 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

2.1 kt → V_(mph)

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

V_(mph) = 2.1 kt × 1.1507794480225 mph

V_(mph) = 2.4166368408474 mph

The final result is:

2.1 kt → 2.4166368408474 mph

We conclude that 2.1 knots is equivalent to 2.4166368408474 miles per hour:

2.1 knots = 2.4166368408474 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 0.41379821042924 × 2.1 knots.

Another way is saying that 2.1 knots is equal to 1 ÷ 0.41379821042924 miles per hour.

Approximate result

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

2.1 kt ≅ 2.417 mph

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