OT Knots to MPH

super99 · May 1, 2016

I bought a Mastech Digital Anemometer to measure wind speed for spraying. The listing showed mil/h and knots plus some other figures to measure wind speed. It came and I put in a battery to try it out. The book lists Knots as nautical miles/hour,1850 meters/hour and mil/h as nautical miles/hour. There is no listing for mph. I tried it in the wind and the knots reading was about 3.5 and then I switched it to mil/h and the reading was about 2.5 How do I go about converting knots to mph, or is the book listing wrong about mil/h? Either that or I can measure kilometer/h and how do I convert that to mph? It seems like nothing I do is easy!! Chris

20 knots is 23 mph. Bob

One knot is 1.151 mph

A nautical mile is 2000 yards.

100 knots is 115 mph.

Easiest way it to just type "convert x mph to knots" into the google search box.

Like stated, 1.15 MPH per knot.

Had a couple rides on an LST...15 knots, they said was about 17 mph. Jump speed in a C 130 is 140 knots....about 160 mph.

Aren't you about 80 feet short there?

"mil/h" is miles per hour. (distance covered divided by elapsed time)

The measurement on the mil/h scale should be slightly higher than on knots. Try it again when the wind is a bit more consistent.

I would never jump out of a perfectly good airplane going 160 mph.

Download this free program. I keep it on my desktop and use it all the time when I need to convert almost anything.

The correct formula, as already stated in several posts below, is knots x 1.15 to convert to mph.

I am a pilot. Current aircraft show airspeed at knots, but some show both. Back about 70's Some were Mph and some were Knots. I was in and out of a lot of different planes. Some times i was slow and Some times hot. LOL

He is, but he is a carpenter and they can cover a multitude of sins with a little trim & caulk.

A nautical mile is based on the circumference of the earth and is one degree of latitude or 6076 feet vs 5280 ft for a statue mile. To get miles per hour, time knots figure by 1.151 to get the conversion factor. Knots/nautical mile data is used in ships and aircraft for planning purposes. I flew for 45 before retiring recently, to include the C-130 so I am used to airborne troops jumping out of aircraft. One time at Bragg the drop was cancelled due to high winds and we went low level instead for training and by the time we got back most of the jumpers in the back had puked all over themselves and the seats in the back due to bumpy ride and some had never landed in a plane before as they were used to taking off and jumping out. C-130 had a great HVAC system to keep them cool in the back which was great in Nam. Except for the T-38, the C-130 was my favorite aircraft.

(quoted from post at 20:07:03 05/09/16) A nautical mile is based on the circumference of the earth and is one degree of latitude or 6076 feet vs 5280 ft for a statue mile.

Not to be picky but it's a minute of latitude that is 6076 feet. A degree is about 69 miles

Thanks for the correction...you are spot on.
