857 knots in kilometers per hour

Result

The conversion result is: 857 knots is equivalent to 1587.164 kilometers per hour.^[1]

Conversion in the opposite direction

The inverse of the conversion factor is that 1 kilometer per hour is equal to 0.000630054613133866 times 857 knots.

It can also be expressed as: 857 knots is equal to 1 / 0.000630054613133866 kilometers per hour.

Approximation

An approximate numerical result would be: eight hundred and fifty-seven knots is about one thousand, five hundred and eighty-seven point one six kilometers per hour, or alternatively, a kilometer per hour is about zero times eight hundred and fifty-seven knots.

Units involved

This is how the units in this conversion are defined:

Knots

"The knot (/nɒt/) 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."

Kilometers Per Hour

"The 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."
