Convert knots to mph


Speed (in knots):
Speed (in mph):

The calculator allows you to convert knots to miles per hour.

Perform the reverse calculation: convert miles per hour to knots

1 knot = 1.15078 mph (approximately equal to)
1 mph = 1 / 1.15078 = 0.86898 knot (approximately equal to)

To convert mph to knots, multiply by 1.15078.

Example 1

We are going to convert a speed s of 30 knots to mph.
Speed s = 30 knots
1 knot = 1.15078 mph
s = 30 knots = 30 x 1.15078 = 34.52 mph

Other examples

To convert knots to miles per hour (mph), you can multiply the knot value by 1.15078. The formula for the conversion is:

mph = knots × 1.15078

Here are four examples of how to convert knots to mph:

A small boat is traveling at a speed of 15 knots. To convert this to mph, we use the formula:
mph = knots × 1.15078
mph = 15 × 1.15078 = 17.26

An airplane is flying at a speed of 500 knots.
mph = knots × 1.15078
mph = 500 × 1.15078 = 575.39

A ship is traveling at a speed of 25 knots.
mph = knots × 1.15078
mph = 25 × 1.15078 = 28.77

A weather report indicates that the wind speed is 35 knots.
mph = 35 × 1.15078 = 40.28

The results are rounded to two decimal places.

The table shows the conversion from knots to miles per hour (mph), with knots listed in the left-hand column and their corresponding mph values listed in the right-hand column. To read a specific value in the table, simply find the row that corresponds to the knot value you're interested in, and then read across to the mph value in the right-hand column. For example, if you want to convert 23 knots to mph, you would find the row with "23" in the left-hand column, and then read across to the right-hand column to find the mph value of "26.47".

Knots

Knots is a unit of speed commonly used in the marine and aviation industries, as well as in meteorology. It measures speed in nautical miles per hour (nm/h), which is equivalent to approximately 1.15 statute miles per hour (mph). One nautical mile is equal to 1.852 kilometers, and it's based on the circumference of the Earth, with one nautical mile being one minute of arc measured along a meridian. The knot is defined as one nautical mile per hour, which means that if a vessel or aircraft travels at a speed of one knot, it will cover a distance of one nautical mile in one hour. Knots are commonly used to measure the speed of boats and ships, as well as the speed and direction of wind in weather reports. They are also used in aviation to measure airspeed, with the airspeed indicator in aircraft displaying speed in knots. When converting knots to other units of speed, it's important to note that one knot is equal to approximately 1.15 mph or 1.852 km/h. To convert knots to mph, you would multiply the knot value by 1.15. Conversely, to convert mph to knots, you would divide the mph value by 1.15.

Miles per hour (mph)

Miles per hour is a unit of speed commonly used in the United States and other countries that follow the imperial system of measurement. It measures the number of miles traveled per hour, or the distance covered in miles over a period of one hour. Mph is often used to measure the speed of vehicles such as cars, trucks, and airplanes. It's also commonly used in weather reports to describe wind speed. In some countries, such as those that use the metric system, kilometers per hour (km/h) is the standard unit of speed. However, mph is still used in some contexts, such as in the UK where it's the legal unit for speed limits on roads. Converting between mph and other units of speed can be useful in certain situations, such as when traveling internationally or when working with scientific data. For example, if you need to convert mph to kilometers per hour, you would multiply the mph value by 1.60934. Conversely, to convert kilometers per hour to mph, you would divide the value by 1.60934.

The symbol for miles per hour is "mph". It's a combination of the abbreviation for miles ("m") and "per hour" ("ph"). When writing or speaking about speed measurements, it's common to use this symbol after the numerical value to indicate the unit of measurement. For example, you might say "the car was traveling at 60 mph" or "the wind speed was 25 mph".
