Of course I'm not comparing the same speed. I could have if I decided to go for a lower number when 'testing' the nautical miles. However it's the conversion I wanted to test, and I don't see any problem with that last test...
Do you mean to say a measurement of .7 nm in 3 min shouldn't give a speed of 14 knots?
That second example was just to show that 3:15 apply to metric->knots but not to imperial...
(I guess I just didn't understand you. :p )
[edit : Ahhh!! I do understand now. Well all distance measurements are in metres and kilometres when using the metric system in game,
but the speed are still in knots. There...
