wind speed conversion required

Paul Beaurain · 30 March 2009, 20:13

Hi
I have been working with a medium term weather forecast and the wind speeds all show in m/s (metres per second).
It would (for me) be easier to work in knots. To assist me in verifying that my conversion is OK , has anyone else got a CONFIRMED conversion ratio/factor.
Thanks
Paul

1 meter a second = 1.94384449 knots

courtesy of google, hope that helps.

Paul, are you looking at this: http://www.ecmwf.int/products/foreca...!2009033012!!/ ?

If so, my experience of it is that it generally gives a good forecast, but the timeframe slips about a bit. I have no "proven" m/sec to Kts tables but experience does suggest that you want to avoid the yellow and green areas!

You guys be careful up there

Google will convert most things for you without hunting for "conversion factors".

e.g. type in the search box "15 m/s in knots" and it tells you 29.157...
or "4000 mm in feet" and it tells you 13.12... ft

etc...

Double the m/s and to all intents and purposes you will have the speed in knots
