Another trick, you can do C->F in your head: Double the centigrade temperature, subtract 10% from the product, and add 32 to get Fahrenheit. 10 degrees C = (2*10-2) + 32 = 50 degrees F
F->C is not so slick, but works: Subtract 32 from the Fahrenheit temperature, add 11% of the result to itself and divide by 2 50 degrees F =((50-32) + 1.98)/2 = 10 degrees C. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
