Relationship between 2 max min values ?

Is there a way to make a relationship between 2 max and min values. This could be either 0 - 1 or 200 - 600, basically a varying max and min, in relation with another set of max and min values, which also vary ?

You probably mean the function “Map Range unclamped” or “Map Range Clamped” which “translates” one Range into another Range.
For Example
Range A [200,300]
Range B [0,1]

Input of 250 will output 0.5

Thanks. I’m guessing that I would do 200 - 300 to 0 - 1, then on the other side just 0 - 1 to 100 - 600 etc.
