722 miles per hour in knots

Result

The conversion result is: 722 miles per hour is equivalent to 627.400846652268 knots.^[1]

Conversion in the opposite direction

The inverse of the conversion factor is that 1 knot is equal to 0.00159387735183316 times 722 miles per hour.

It can also be expressed as: 722 miles per hour is equal to 1 / 0.00159387735183316 knots.

Approximation

An approximate numerical result would be: seven hundred and twenty-two miles per hour is about six hundred and twenty-seven point three nine knots, or alternatively, a knot is about zero times seven hundred and twenty-two miles per hour.

Units involved

This is how the units in this conversion are defined:

Miles Per Hour

"Miles per hour (abbreviated mph, MPH or mi/h) is an imperial and United States customary unit of speed expressing the number of statute miles covered in one hour. Although kilometres per hour is now the most widely used measure of speed, miles per hour remains the standard unit for speed limits in the United States, the United Kingdom, Antigua & Barbuda and Puerto Rico, although the latter two use kilometres for long distances."

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."
