Resistor Color Code Calculator
한국어Pick the bands you see, left to right. You get the resistance and tolerance.
Not sure which end is band 1? Enter them as you see them. If you read it backwards, we flip it and tell you.
Example: Yellow, Violet, Red, Gold reads 4.7 kΩ, ±5% tolerance.
Bands
Count the bands first. No tolerance band means 3 bands.
Band 1 color (digit)
Every slot takes all 13 colors. Enter what you see and we check the direction.
Pick every band and the value shows up right below.

What this calculator doesn't do
Colors look different on every screen. The swatches here are a guide, and the standard says the same about its own.
Faded or burnt parts are easy to misread. Check with a multimeter.
Some makers use their own charts. This one follows IEC 60062 only.
