How many kilometers per hour in 455 knots?

Conversion formula

The conversion factor from knots to kilometers per hour is 1.8519999999969, which means that 1 knot is equal to 1.8519999999969 kilometers per hour:

1 kt = 1.8519999999969 km/h

To convert 455 knots into kilometers per hour we have to multiply 455 by the conversion factor in order to get the velocity amount from knots to kilometers per hour. We can also form a simple proportion to calculate the result:

1 kt → 1.8519999999969 km/h

455 kt → V_(km/h)

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

V_(km/h) = 455 kt × 1.8519999999969 km/h

V_(km/h) = 842.6599999986 km/h

The final result is:

455 kt → 842.6599999986 km/h

We conclude that 455 knots is equivalent to 842.6599999986 kilometers per hour:

455 knots = 842.6599999986 kilometers per hour

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer per hour is equal to 0.0011867182493552 × 455 knots.

Another way is saying that 455 knots is equal to 1 ÷ 0.0011867182493552 kilometers per hour.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four hundred fifty-five knots is approximately eight hundred forty-two point six six kilometers per hour:

455 kt ≅ 842.66 km/h

An alternative is also that one kilometer per hour is approximately zero point zero zero one times four hundred fifty-five knots.

Conversion units

The units involved in this conversion are knots and kilometers 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.

Kilometer per hour

The kilometre per hour (American English: kilometer per hour) is a unit of speed, expressing the number of kilometres travelled in one hour. The unit symbol is km/h. Worldwide, it is the most commonly used unit of speed on road signs and car speedometers. Although the metre was formally defined in 1799, the term "kilometres per hour" did not come into immediate use – the myriametre (10,000 metres) and myriametre per hour were preferred to kilometres and kilometres per hour.
