678 kilometers per hour in knots

Result

The conversion result is: 678 kilometers per hour is equivalent to 366.090712742981 knots.^[1]

Conversion in the opposite direction

The inverse of the conversion factor is that 1 knot is equal to 0.00273156342182891 times 678 kilometers per hour.

It can also be expressed as: 678 kilometers per hour is equal to 1 / 0.00273156342182891 knots.

Approximation

An approximate numerical result would be: six hundred and seventy-eight kilometers per hour is about three hundred and sixty-six point zero eight knots, or alternatively, a knot is about zero times six hundred and seventy-eight kilometers per hour.

Units involved

This is how the units in this conversion are defined:

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."

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."
