Km.--Miles converter
#41
It's too hot to absorb all this math-- at least it is in Fahrenheit. If I were in Europe, it would be cooler (Centigrade). Speaking of which, if Kelvin and Celsius degrees are the same, why do they have different names? And why are Celsius and Centigrade different names, but the same scale?

tomboy - Kelvin and Celsius degrees are the same size, but the scales are different. Zero on the Celsius scale is the freezing point of [pure] water. Zero on the Kelvin scale is absolute zero - the point at which all molecular motion ceases. Zero degrees Kelvin is minus 273 Celsius - or, conversely, zero Celsius is 273 Kelvin. The equivalent of Kelvin using Farenheit degrees is Rankin, and absolute zero on the Rankin scale is about minus 460 Farenheit. Farenheit, Rankin (he actually spelled it Rankine), Celsius, and Kelvin were all scientists - centigrade is an improper term for the Celsius scale.
Interesting fact - there's only one temperature that's the same on both the Farenheit and Celsius scales - minus 40.

allisonm,
I convert C to F by taking the C, doubling it, then add 30. Then obviously F-30 divide by half = C
So 30C is approx 80F. It's approx expecially in the extreme numbers but it gets the job done.

Celsius was named for a scientist.
Centigrade is the numbering system.
Kelvin is based on absolute zero.
Celsius is based on water freezing.
Go to Google. Type in
26 miles in kilometers
3000000 kilometers in miles
98.6 fahrenheit in celsius
20 celsius in fahrenheit

All this math makes me woozie.
I still use the system I learned in the service. For converting Km to miles, divide by two and add a few.
To convert Celsius to F., just double and add 30. In reverse, divide the F. by 2 and subtract 30. It's close enough.

I am mathematically challenged but at least I am having a few laughs here tonight. Thank you all. (Lucygirl, that is much easier to remember! I was thinking about our last trip to Ireland when it was always about 14 degrees - 58 seems much warmer!)
