Resistor Value Calculator

Calculate resistance from two significant digits and a multiplier band.

Resistor Value

How this calculator works

This mirrors the standard 4-band resistor color code numerically — the first two bands are significant digits, the third is the multiplier power of ten.

Formula

resistance = (digit1×10 + digit2) × 10^multiplier
