Resistance Calculator


Use this calculator to find the closest match to a desired value using up to 4 standard resistor values. The desired value can contain "k" for kΩ or "M" for MΩ as a suffix. You can set the standard resistor value range to use from E6 to E192 and the percent accuracy of the result. You can also use this calculator to work out the value of up to four resistors in parallel. Again, you can use "k" and "M" as a suffix in the values to simplify entry.
