 Is there a way to take fps that a plane or object is going and find out what the speed is of the plane or object.  it would realy help me out.THANKS!!!!!! -BryanBecker

 Hey, have you ever been to school or what?   Anyway, the conversion factor is around 2!!! for instance: wind is reported to be 10 meters per second (done so in Eastern Europe). How much is that in knots? Answer: 20 kts! You want the prove of this? 10 MPS = 36000 MPH (since there are 3600 seconds in 1 hour) = 36KMPH (since there are 1000 meters in 1KM) = 20 KTS (since 1KT = 1NMH and 1NM = +/- 1.8KM) I hope you see how easy this is.

 I've only now noticed you asked for the conversion factor of FPS ,ot MPS, to KTS. However, the system remains the same. Since: 3.3 FT = 1M you'd have to devide the above conversion factor by 3,3 to find the new value. So 0,6 would be a fine value. That's really all there is to say about it.

 Bryan, one statute mile is 5300 feet (roughly, the exact number you will have to ask an American about, I never use feet and I never use miles). An hour is 3600 seconds - exactly - that counts in metric countries too! So take your fps, divide by 3600, multiply by 5300, and the result is mph - roughly. Or multiply by 1.47 (5300 / 3600) - roughly, even more so. If on the other hand you want to convert knots (nautical miles per hours), then one Nm = roughly 6080 feet, so the factor becomes roughly 1.69 instead. You might also go metric and measure speeds in m/s or km/h. Then the factor is 3.6 - not roughly, but exactly! And all your troubles would be gone.   Best regards, Preben Norholm

 Oh no, I divided where I should have multiplied and visa versa. Somehow Sabenapilot got it almost right (even if it is beyond me how he managed that). So the factors are: fps -> mph: 0.68 (3600 / 5300) fps -> knots: 0.59 (3600 / 6080) The factors in my former post are valid for converting mph to fps or knots to fps. You should go metric. At least you could start doing it inch by inch. Cheers, Preben Norholm

 Preben, FYI a statute mile is 5280 ft. Greg

 Tnx a lot Greg. As a metric guy I had to walk around a few metric conversions, and my rough figure came out at 5292.7631 feet. I will try to remember 5280, at least until tomorrow. I counted one foot as 0.304 m, but 0.3047 m is a better value. Must be since I know that a yard (3 feet) is pretty close to 0.914 m. It would have landed me on 5280.6038 feet. Happy landing, Preben Norholm

 Can I ask why you want to convert vertical velocity expressed in FPM in to Speed?

 Ahhh, give Bryan a break. Just a little one? We were all absent from one time to another in school, maybe he was absent the day they talked about that?   You know, if you take the speed of a .45Cal. bullet in FPS which is close to 700FPS and figure it into MPH you should come close to the speed of a fast jetliner with a fair tail wind?

 It's the new math Max. It doesn't matter what the answer is as long as you feel good about it.
