help with speed
 

hi all i am not to good at reading speed in knots does 10 knots = 10 mph???:roll: etc etc...

There's a truckload of websites out there that will help with doing conversions. Here's one for instance http://www.onlineconversion.com/

1 knot is 1 nautical mile per hour, which is ever so slightly different from a standard mile per hour measurement, in that it takes into account the curvature of the earth.

You can equate it to having to travel slightly further to get from point A to point B if you had to go over a hill en-route, as opposed to going in a flat straight line.

As all speed measurements are arbitrary, it shouldn't matter. It is just something to get used to.

If you need an ingame measurement of knots vs time, draw out a 10km line from your current position and straight ahead. Experiment with speed settings, and you will see how long it will take you to get there. You could translate this to km/h, but it is rather pointless.

Just make a note that under say X knots you will reach intercept course Y in 10 hours, and under Z knots intercept course Q in ten hour (Do this during an egress from home base at constant speed of X or Z. Use the pencil, mark an X at original position when you've reached target speed of X or Z. Then trod along in a straight line for ten hours, and measure distance traveled). Keep it simple, 10 and 15 knots are perfectly good values for X and Z. Makes for a great guide when trying to intercept targets from some radio contact. Especially as contacts reported medium speed (as is most common) means 6-8 knots. Plot a course some 25% ahead of worst case scenario (that is a somewhat fast target) at your preferred or necessary speed based upon the calculations, and track down projected target course until contact is made.

Bingo should then be your name :arrgh!:

that pretty much sums it up

Well, 1 knot is 1 nautical mile per hour. Now, one statute (normal) mile is 5280 ft., but 1 nautical mile is 6000 ft.

So 1 knot is 6000 ft. per hour. As 3ft = 1 yard, then 1 nautical mile = 2000 yards

1 knot is 2000 yards per hour.

thanks i just get my calculator :rotfl: :lol:

Not (or knot) quite. According to the International Hydrographic Conference of 1929, nautical mile is exactly 1582 meters, or 6076.1155 feet, or 2025.372 yards.

I've got a big blackboard in front of me with 1.85 written on it as I keep forgetting that number.
I'm playing with kmph and I'm using the 3:15 rule to calculate speed atm. Working fine for me.

How many inches is .1155 feet ?
