How many knots in 87.1 kilometers per hour?

Conversion formula

The conversion factor from kilometers per hour to knots is 0.53995680345662, which means that 1 kilometer per hour is equal to 0.53995680345662 knots:

1 km/h = 0.53995680345662 kt

To convert 87.1 kilometers per hour into knots we have to multiply 87.1 by the conversion factor in order to get the velocity amount from kilometers per hour to knots. We can also form a simple proportion to calculate the result:

1 km/h → 0.53995680345662 kt

87.1 km/h → V_(kt)

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

V_(kt) = 87.1 km/h × 0.53995680345662 kt

V_(kt) = 47.030237581072 kt

The final result is:

87.1 km/h → 47.030237581072 kt

We conclude that 87.1 kilometers per hour is equivalent to 47.030237581072 knots:

87.1 kilometers per hour = 47.030237581072 knots

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 knot is equal to 0.021262916188254 × 87.1 kilometers per hour.

Another way is saying that 87.1 kilometers per hour is equal to 1 ÷ 0.021262916188254 knots.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that eighty-seven point one kilometers per hour is approximately forty-seven point zero three knots:

87.1 km/h ≅ 47.03 kt

An alternative is also that one knot is approximately zero point zero two one times eighty-seven point one kilometers per hour.

Conversion units

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

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.

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.
