## How many knots is a mile per hour?

A mile per hour is slower than a knot. 0.869 knots is the same velocity as one mile per hour. A mile per hour is 86.90% the velocity a knot. An object moving at a knot is 15.08% faster than an object traveling at one mile per hour.

## Miles per hour to knots conversion factor and formulas

Formula

The conversion factor between miles per hour and knots is 1.151. This represents the ratio of miles per hour per one knot. To calculate the value in knots, we can either divide by the conversion factor or multiply by its inverse.

### Division

To convert from miles per hour to knots, divide miles per hour by 1.151.
The formula is expressed as:
mph ÷ 1.151 = kn

### Multiplication

Alternatively we can multiply by the inverse conversion factor to get the same result.
The inverse of 1.151 is 1/1.151 or 0.869. To convert from miles per hour to knots, multiply miles per hour by 0.869.
The formula is expressed as:
mph × 0.869 = kn

To convert 222 miles per hour to knots, divide 222 miles per hour by 1.151.
222 mph ÷ 1.151 = 192.913 kn

## How fast are 222 miles per hour?

Real world scale examples to visualize the velocity of 222 miles per hour / 192.913 knots

• 1.11 times the typical speed of modern high speed train (200 mph)
• 40% of the typical cruising speed of a passenger jet (560 mph)
• 31% of the speed of a typical .22 caliber bullet (720 mph)

When converting from from miles per hour to knots, both units are within the US Customary / UK Imperial system and conversion factors are governed by standards set by the controlling body.

Customary/Imperial Unit

Miles per hour is a velocity measurement within the US/UK Imperial systems. It is defined as the number of miles traveled in one hour. MPH is frequently used for measurement and regulation of vehicle speed limits in the US, UK and many British dependencies. The common symbols for miles per hour are mph, MPH or mi/hr.

Customary/Imperial Unit

Knots are a measure of speed over long geographic distances most often associated with the maritime and aviation communities. A knot is a measurement of distance traveled in nautical miles in one hour. The origins of the knot derive from practice of mariners throwing a wooden chip log attached to a line off the stern of a ship. As the ship traveled forward, the line spooled out and the number of physical knots on the line where counted over a 30 second period to determine boat speed. The symbol for knots is either kn or kt.
