This is the best and by far the fastest and most easy Resistor Color Code calculator. (This is the version without advertising)

Calculate resistor value by selecting the band colors.

Or Reverse:

Enter a resistor value and find the color code.
If the value is not an standard E-series value the two nearest values are shown.

* 3, 4, 5 and 6 band resistor support *

If the resistor has a standard E-series value then also the E-series (E3, E6,E12, E24, E48, E96, E192) number will be shown.
