Calculate the equivalent Percentage for any given current signal 4 to 20 mA. For conversion, we need transmitter’s Lower Range Value and Upper Range Value.
Formula:
Where
X is current signal in mA
Example:
Percentage % = ((X-4)/16)(100)
Percentage % = ((13-4)/16)(100)
Percentage % = 56.25

Very good post
Really Helpfull...!

Thank you so much, this finally makes sense to me.
The -25 part was very unclear - I understand the value doesn't start at 0 but you just came up with -25 from 4-20?!
