Standard Resistor Value Calculator



This Excel resistor calculator rounds arbitrary resistance values to the closest EIA standard resistor values. Choose between 20%, 10%, 5%, 2%, 1% and 0.1% EIA standards. An optional argument allows for rounding to the closest numerical value, or the closest ratiometric value. For instructions, see the online article ”Calculate Standard Resistor Values in Excel” at Electronic Design.
