18 knots is equivalent to 33.336 kilometers per hour.

The inverse of the conversion factor is that 1 kilometer per hour is equal to 0.0299976001919846 times 18 knots.

It can also be expressed as: 18 knots is equal to 1 0.0299976001919846 kilometers per hour.

Approximation

An approximate numerical result would be: eighteen knots is about thirty-three point three four kilometers per hour, or alternatively, a kilometer per hour is about zero point zero three times eighteen 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."

[1] The precision is 15 significant digits (fourteen digits to the right of the decimal point).
