How many knots in 97.8 miles per hour?

Conversion formula

The conversion factor from miles per hour to knots is 0.8689762419014, which means that 1 mile per hour is equal to 0.8689762419014 knots:

1 mph = 0.8689762419014 kt

To convert 97.8 miles per hour into knots we have to multiply 97.8 by the conversion factor in order to get the velocity amount from miles per hour to knots. We can also form a simple proportion to calculate the result:

1 mph → 0.8689762419014 kt

97.8 mph → V_(kt)

Solve the above proportion to obtain the velocity V in knots:

V_(kt) = 97.8 mph × 0.8689762419014 kt

V_(kt) = 84.985876457957 kt

The final result is:

97.8 mph → 84.985876457957 kt

We conclude that 97.8 miles per hour is equivalent to 84.985876457957 knots:

97.8 miles per hour = 84.985876457957 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.011766661022725 × 97.8 miles per hour.

Another way is saying that 97.8 miles per hour is equal to 1 ÷ 0.011766661022725 knots.

Approximate result

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

97.8 mph ≅ 84.986 kt

An alternative is also that one knot is approximately zero point zero one two times ninety-seven point eight miles per hour.

Conversion units

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

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.

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.
