Getting Scaled Groov Data into Node-RED

[born2see]

Thanks guys! In this case the Range node works perfectly for me because it mimics the scaling in Groov and allows me to get my scaled 4-20 mA data without all that hard math.

Here is a post showing how to do it manually:

4-20mA Conversion Formula

I have a sensor which gives me a raw input of the range 4000-20000. This represents a scaled range of 0-1450. Can anyone give me a formula that will allow me to calculate the scaled value from the raw one. I’ll make up an example: I get a raw reading of 12456. How do I convert that to a scaled value? I know you can do it in Groov with the scaling tool but I need to do it as a formula. Thanks, Dave

Thanks
