863 knots in feet per second

Result

The conversion result is: 863 knots is equivalent to 1456.57990667833 feet per second.^[1]

Conversion in the opposite direction

The inverse of the conversion factor is that 1 foot per second is equal to 0.000686539746576937 times 863 knots.

It can also be expressed as: 863 knots is equal to 1 / 0.000686539746576937 feet per second.

Approximation

An approximate numerical result would be: eight hundred and sixty-three knots is about one thousand, four hundred and fifty-six point five seven feet per second, or alternatively, a foot per second is about zero times eight hundred and sixty-three 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."

Feet Per Second

'The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s, or sec). The corresponding unit in the International System of Units (SI) is the metre per second.Abbreviations include ft/s, ft/sec and fps, and the rarely used scientific notation ft s−1.'
