4 Band Resistor Color Code Calculator

This tool helps you decode the resistance of 4-band resistors using their color code. Select the color of each band to calculate resistance in ohms (Ω) along with the tolerance.

First Band: Black Brown Red Orange Yellow Green Blue Violet Gray White Second Band: Black Brown Red Orange Yellow Green Blue Violet Gray White Multiplier: Black (×1 Ω) Brown (×10 Ω) Red (×100 Ω) Orange (×1 kΩ) Yellow (×10 kΩ) Green (×100 kΩ) Blue (×1 MΩ) Violet (×10 MΩ) Gray (×100 MΩ) White (×1 GΩ) Gold (×0.1 Ω) Silver (×0.01 Ω) Tolerance: Brown (±1%) Red (±2%) Green (±0.5%) Blue (±0.25%) Violet (±0.10%) Gray (±0.05%) Gold (±5%) Silver (±10%)
