Input Raw to unit
The math used to convert from the raw input value to a real world unit. The
symbol “x” represents the unconverted input value in the equation.
DO NOT LEAVE THIS BOX BLANK.
It has to contain valid math to
provide a value to the input. If unsure, just enter “x” in this box.
The math boxes must to contain valid math expressions.
The input raw value is represented by a lower case ‘x’.
Unit to input Raw
The math used to convert from the real world unit back to the raw input
value. This should be the
inverse function
of the Input Raw to Unit function.
Examples of inverse functions:
Input Raw to Unit
Unit to Input Raw
x*10
x/10
x*5+32
(x-32)/5
5000/x
5000/x
Simply speaking, if you take the output from the first function for any value
of x, and plug that into the x of the second, you should end up with the value
you started with.
If a “WARNING” text is displayed next to Verification, this means the
second math is not the inverse function of the first. Please correct the math.
