Anyone know of a quick way to rescale a variable or value into something else ? (ex: Degrees Celcius to Ferenheit and back) or anything else.
Temperature requires a formula (Divide by 5, then multiply by 9, then add 32) and the other way around.
Rescale a value (ex: 0-10 rescaled to 0-100) would be different, but linear
Maybe a User App someone as created or RM ?
For temperature there are a few built in methods that make it easier.
- celsiusToFahrenheit
- fahrenheitToCelsius
- getTemperatureScale
- convertTemperatureIfNeeded (I use this one a lot)

Rescaling linear values I find much easier with simple formula and adjust it as needed. You could probably make a generic method to handle linear scaling.

Thank-you @gavincampbell, I will look into this, so this is all done with Groovy ?
