Knots to mph Converter

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.

Conversion formulas. Knots to mph and mph to knots

You may use our knots to mph converter or use the formula below to manually convert between speed units:

Knots to mph and mph to knots

Knots and km/h

V_{knots}= 0.539957 * V_(\frac{km}{h})\newline V_\frac{km}{h}=1.852 * V_{knots}

Knots and ft/s

V_{knots}= 0.592484 * V_\frac{ft}{s}\newline V_\frac{ft}{s}=1.687810 * V_{knots}

Knots and m/s

V_{knots}=1.943844 * V_\frac{m}{s}\newline V_\frac{m}{s}= 0.514444 * V_{knots}

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).

How to use knots to mph converter: 3o knots to mph example

Take a look at this brief step-by-step example to see how fast a knot – or, for example, 30 knots – is:

1. Consider the unit you’d want to convert. Let’s pretend we’re trying to convert 30 knots to miles per hour.
2. Fill in the appropriate box with the value. In our scenario, the first component of the tool requires us to input 30.
3. 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!
