thanx [VxE] , example sounds good, beep command exist also for the old calculator, soundcard is ok
I have formula from a book, hope it's ok

Just take a simple calculator and

To Convert Centigrade to Fahrenheit – 1.8 multiplied by the Centigrade figure and then add 32 to it

To Convert Fahrenheit to Centigrade – Minus 32 from the Fahrenheit figure and then divide by 1.8

Much ado about nothing…

You did not get it. Not the formula is interesting (see my first post here) but the ability to include the function in a script without looking up the algorithm. Your script can pop-up an input box or, when a temperature value is selected in your document, it can convert it and write it back at a press of a hotkey. Starting a calculator is far too slow, and you need to remember the formula.
