How many miles per hour in 120.6 knots?

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 120.6 knots into miles per hour we have to multiply 120.6 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

120.6 kt → V_(mph)

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

V_(mph) = 120.6 kt × 1.1507794480225 mph

V_(mph) = 138.78400143152 mph

The final result is:

120.6 kt → 138.78400143152 mph

We conclude that 120.6 knots is equivalent to 138.78400143152 miles per hour:

120.6 knots = 138.78400143152 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 0.007205441475136 × 120.6 knots.

Another way is saying that 120.6 knots is equal to 1 ÷ 0.007205441475136 miles per hour.

Approximate result

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

120.6 kt ≅ 138.784 mph

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

Conversion units

The units involved in this conversion are knots and miles per hour. This is how they are defined:

Knot

The knot is a unit of speed equal to one nautical mile (1.852 km) per hour, approximately 1.151 mph. The ISO Standard symbol for the knot is kn. The same symbol is preferred by the IEEE; kt is also common. The knot is a non-SI unit that is "accepted for use with the SI". Worldwide, the knot is used in meteorology, and in maritime and air navigation—for example, a vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Etymologically, the term derives from counting the number of knots in the line that unspooled from the reel of a chip log in a specific time.

Mile per hour

Miles per hour (abbreviated mph, MPH or mi/h) is an imperial and United States customary unit of speed expressing the number of statute miles covered in one hour. Although kilometres per hour is now the most widely used measure of speed, miles per hour remains the standard unit for speed limits in the United States, the United Kingdom, Antigua & Barbuda and Puerto Rico, although the latter two use kilometres for long distances.
