KATO33 0 #1 March 31, 2002 What's the difference when referring to wind speed between MPH and Knots??And what’s the formula ? Quote Share this post Link to post Share on other sites
QuickDraw 0 #2 March 31, 2002 MPH x 0.87 (roughly) = knotsSo 120 kts x .87 = 104.4 mphWhy do we use knots ? i think it's from naval times when their speed was estimated by a knotted rope tied to a float,and aircraft being ship's of the sky carried on using the term.Please correct me if i'm wrong. ..Billions of people living out their lives..Oblivious..

FallinWoman 1 #6 April 1, 2002 QuoteMPH x 0.87 (roughly) = knotsSo 120 kts x .87 = 104.4 mphOk, the math teacher in me is reawakening after my weeklong cruise.....On the first equation you have MPH being multiplied by a facter less than one to get a smaller number for knots.On the second equation, you switch it around, saying that the knots number is higher than the MPH number....ONe of those equations is wrong, it needs to be division or to switch the palcement of MPH and knots in the equation.Is this too nerdly???Anne Quote Share this post Link to post Share on other sites

Then I realised his number was correct..._AmICQ: 5578907MSN Messenger: andrewdmetcalfe at hotmail dot com AIM: andrewdmetcalfeYahoo IM: ametcalf_1999 Quote Share this post Link to post Share on other sites
QuickDraw 0 #8 April 1, 2002 Good point, somewhere in there you need to divide,Maths is not one of my stronger points.

That would never happen - I mean, that's almost as silly as suggesting that screwing up a units calculation could cause a 757 to run out of fuel, or even a spacecraft to crash into Mars!-bill von Quote Share this post Link to post Share on other sites

quade 4 #12 April 1, 2002 Quote1 nmile = 6076'Well, technically no.1 international nautical mile = 1.852 km = 1.1508 miles = 6076.1155 feet The international nautical mile is also known as the international air mile. The geographical nautical mile is 6080 feet (0.064% larger).quadeRef http://crsp3.nrl.navy.mil/creme96/cm/Nautmile.htmhttp://futurecam.com Quote Share this post Link to post Share on other sites
