Standard Resistance Finder
| Desired Resistance | The exact resistance you want to find. |
| Series | Closest Resistance (Ω) | Percentage Error (%) | Closest Equal Or Lower Resistance (Ω) | Percentage Error (%) | Closest Equal Or Higher Resistance (Ω) | Percentage Error (%) |
|---|---|---|---|---|---|---|
| E6 | ||||||
| E12 | ||||||
| E24 | ||||||
| E48 | ||||||

| E192 |
What Is This?
Enter your desired resistance, and this calculator will find the closest preferred value (purchasable resistance) in each one of the EIA E series, from E6 to E192. The percentage difference between your desired resistance and the preferred value is also shown for each E series.
More information on the E series can be found at http://www.mbedded.ninja/electronics/components/resistors#the-e-series.
Accuracy
Note that although the E48 series has more values per decade than say, the E24 series, you might find a closer resistance in the E24 series due to the E6, E12 and E24 using a different number sequence to the E48, E96 and E192 series.
If your desired resistance is exactly half-way (in percentage terms) between two preferred values, this calculator will choose the higher resistance.
