Dear anglo-saxons & yankees, is there anywhere a list, a web page in the net, which would help a Frustrated Finn to compare knots to metres/second or to kilometres/hour? Unfortunately, I am getting confused quite often, having been used to metric system. Happens both ways, Iīve noticed... Same thing with miles: fortunately I did not sleep during ALL my primary or secondary school lessons, I suppose it goes with feet like this: 1 ft = 33 centimetres & with inches itīs 1' = 2,5 centimetres....

The defining link to the metric (SI) system of length measurements is this: 1 inch = 2.54 cm defined to be exact in fact, the (stupid) english (or american standard) system is now defined in terms of the metric (read: much more useful) system. To convert: from any english system to any metric system, or vice versa, use the relationships above (and a few math skills). To convert from the nautical system, which is based on the distance between lines on the earth (60 Nautical Miles = the distance between the latitude lines on the earth drawn 1 degree apart). There are 90 degrees of latitude between the earth's Equator and the True North Pole. Now, the radius of the earth is 6,370, 000 meters and 1/4 of the circumference (2 Pi times the diameter) is .25 x 2 x 3.141592654 x 6,370,000 =10,005,972.6 metres. Ok, now divide this by 90 and get 111177.4734. Now divide this by 60 to get 1853 meters (1.85 km) per Nautical mile. Oh, hell, I have been in the clkassroom way too long. *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************

Thank You all - the Paddlewise did work quite fast with this one! Now all I do need is a laptop when maybe trying something someday along your coastal line: think about weather brodcasts :-p (Alas, those French, they wanted so badly to set a line between Europeans and uppity Yankees - and maybe they were not having very specially close & warm relations to the Brits at the 1800īs...) Somebody should ask Mr. Gingrich what is a metric system - it might arouse some interesting subjects of conversation ;-) Ari Saarto "Donīt praise my English - I do start sllippinggn" Kannaksenkatu 22 / P.O. 92 15141 Lahti - Finland - Europe GSM +358 - 50 - 526 5892 fax. +358 - 3 - 828 2815 e-mail: asaarto_at_lpt.fi *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************
Ari wrote: (SNIP about conversion - units rather than religous)) Here in Canada we are expected to be fluent in two languages (never know that from my French) as well as two measurement systems plus must be able to spell in two versions of English (Americans don't use enough "u's"). Worst of all, we have to understand two interrogative grunts ("Eh" and "Huh"). Any wonder we are so screwed up. By the time we figure out what is going on it is too late. Some one will surely have supplied the proper conversion factors but most of the me one doesn't much care about precision so here is my quick and dirty method. Multiply 1 knot by 0.6 to get feet/second, 0.5 to get kilometres/ hour, 2.0 to get meters/sec, and 0.9 to get miles/hour. These units become a big problem occasionally. We hear a lot about the hull speed and that it is 1.34 *LWL^.5 but this is only true if the units are feet and knots. It is 1.55 * LWL^.5 if you use feet and Miles per hour and 1.25*LWL^.5 in metric units and 2.4*LWL^.5 if you use knots and meters. This is why I prefer the Froude number which is constant for any consistent set of units. The Froude number is V=(g*LWL)^.5 where g is the acceleration due to gravity. So long a one knows that the typical paddling speed range is between Fn 0.23 and Fn 0.30 and that racing paddlers peak out at 0.60 it is easy to handle.

Only two interrogative grunts? There are about a hundred more you will need to learn then John, to talk fluent American Dana At 07:42 AM 3/12/98 -0500, John Winters wrote: >Ari wrote: > >(SNIP about conversion - units rather than religous)) > >Here in Canada we are expected to be fluent in two languages (never know >that from my French) as well as two measurement systems plus must be able >to spell in two versions of English (Americans don't use enough "u's"). >Worst of all, we have to understand two interrogative grunts ("Eh" and >"Huh"). >Cheers, >John Winters >Redwing Designs >Specialists in Human Powered Watercraft >http://home.ican.net/~735769/ *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************
