Calculating the equivalent milliamp value for any given percentage of signal

Formula for calculating the current 4-20ma from equivalent percentage.

Formula to Calculate 4-20ma from percentage

You can use our Instrumentation tool for converting Percentage to 4-20 ma. Click here.

Formula:

Current (mA) = [(16 ma)(X/100)]+4

Where “X” is desired percentage of signal

 Example:

calculate the ma for 40 % of signal

Current (mA) = (16 ma)(x/100)+4
                                    = (16)(40/100)+4
                                    = 10.4 ma
