Quick Answer • How do I convert knots to mph?

mph = kn × 1.15077944802 — so 1 kn = 1.1507794 mph and 60 kn = 69.046767 mph. Reversed, kn = mph × 0.868976241901, giving 1 mph = 0.86897624 kn.

Knots to Miles per hour using the same factor table the full converter uses. The formula is shown with the result, the table below works it through 10 values, and the reverse direction is one click away.

1. How to convert knots to mph

The conversion is a single multiplication: mph = kn × 1.15077944802. Both units are defined against the same base — the metre per second (m/s) — so the factor is fixed and the result is exact to the precision shown.

Worked at the two values people ask for most: 1 kn = 1.1507794 mph and 60 kn = 69.046767 mph. Going the other way, kn = mph × 0.868976241901, so 1 mph = 0.86897624 kn — a direction with its own page, mph to knots.

Results are given to eight significant figures. That is more precision than most jobs need — for a rough figure, treat 1 kn as about 1.1507794 mph and adjust — but rounding early and multiplying afterwards is how a small error becomes a visible one, so the full figure is what the converter carries.

Every row is the same factor applied — nothing in the table is a special case, and any value in between behaves the same way. Type your own figure into the converter above and the Formula tile shows the arithmetic being used, so the result is checkable rather than taken on trust.

3. What the two units are

  • Knots (kn). One kn is 0.51444444 m/s.
  • Miles per hour (mph). One mph is 0.44704 m/s.

Both are converted through the metre per second (m/s): the value is multiplied by its own unit's factor to reach the base, then divided by the target unit's factor to leave it. No direct knots to mph factor has to exist or be kept correct, which is also why the converter can show the same value in all 5 speed units at once.

Speed converts through metres per second. A knot is one nautical mile per hour, which makes it exactly 1.852 km/h — the reason aviation and shipping still use it is that one knot for one hour is one minute of latitude, so it maps onto a chart without arithmetic.

If the pair you actually want is not this one, the full unit converter runs every 5 speed units off the same factor table, along with 11 other categories of measurement.

Worth knowingA knot is one nautical mile per hour, and a nautical mile is exactly 1,852 m — one minute of latitude. That is why it survives in aviation and shipping where the statute mile does not.

4. Knots to Miles per hour FAQs

How do I convert knots to mph?

Multiply by 1.15077944802. 1 kn = 1.1507794 mph, and 60 kn = 69.046767 mph. The factor is exact to the precision shown, so the only rounding is the one you choose to do at the end.

How many mph is 1 kn?

1 kn = 1.1507794 mph. The full formula is mph = kn × 1.15077944802, and 1 mph = 0.86897624 kn going the other way.

What is 60 kn in mph?

60 kn = 69.046767 mph. The table above works the same factor through 10 values, and the converter takes any figure you type — including decimals.

How do I convert mph to knots?

kn = mph × 0.868976241901, so 1 mph = 0.86897624 kn. Use the Swap button in the converter to reverse the direction without retyping the value, or open the dedicated mph to knots page.

What exactly is a knot?

One nautical mile per hour, and a nautical mile is exactly 1,852 metres — one minute of latitude. That makes a knot exactly 1.852 km/h, and it is why aviation and shipping still use it: an hour at one knot moves you one minute up the chart.

Is anything I type sent to a server?

No. The factor table ships with the page and every conversion runs in your browser. Nothing is uploaded, logged or written to storage, and the converter keeps working offline once the page has loaded.
