You’ve come to the right spot if you’re wondering how much a knot is worth; this knots to mph converter will clear things up for you. Simply enter the figure into the calculator, and you’ll have the response in mph, ft/s, m/s, and km/h in the blink of an eye. You may convert mph to knots or any other wind speed unit with our calculators since they are versatile. If you’re wondering how many miles per hour a knot is or how quick it is, keep reading. There’s also a helpful wind speed chart and all the formulae for converting wind speed units.

## How many mph is a knot and how fast is it? What is a nautical mile?

We define knot as **one nautical mile per hour** and includes the following:

- 1.15078 miles per hour (approximately)
- 1.852 kilometers per hour (exactly)
- 1.68781 feet per second (approximately)
- 0.51444 meters per second (approximately)

In meteorology, aviation, and nautical navigation, nautical miles and knots are the units of measurement. So what’s the distinction between the two? The distance is measured in nautical miles, while the speed is measured in knots.

Historically, one nautical mile was defined as one minute of latitude (1/60 of a degree of latitude), or 1.852 kilometers. Because the Earth is a geoid rather than a perfectly spherical, this is the average value.

## Wind speed chart

Knowing how to convert knots to mph can come in handy in a variety of scenarios, such as:

- calculating the boat and airspeeds (for example, check our true airspeed calculator)
- Tidal streams, river currents, and wind speeds are all shown.
- Finding the best windsurfing or kiteboarding conditions (6-30 knots is a range usually used, depending on the body weight, kite size, and skill).

**Consider the unit you’d want to convert**. Let’s pretend we’re trying to convert 30 knots to miles per hour.**Fill in the appropriate box with the value**. In our scenario, the first component of the tool requires us to input 30.**That concludes our discussion. Our knots to mph converter worked perfectly**. We now know that 30 knots equals 34.52 miles per hour. That’s a lot!

## Frequently Asked Questions

**How fast is a knot compared to mph?**

**One knot** equals one nautical mile per hour or roughly 1.15 statute mph. The term knot came from the 17th century when sailors used a device called a “common log” to measure the pace of their ship. A rope with regular knots linked to a piece of wood shaped like a slice of pie was the most typical log.

**How to convert knots to mph formula**

Multiply the speed by the conversion ratio to convert a knot measurement to a mile per hour measurement. For example, the knots multiplied by 1.150779 equals the speed in miles per hour.
