a 4-band part the value is (10 × digit1 + digit2) × 10^multiplier ohms; 5- and 6-band parts add a third significant digit for tighter precision (and, on 6-band parts, a temperature-coefficient band). Each colour maps to a fixed number: black 0, brown 1, red 2, orange 3, yellow 4, green 5, blue 6, violet 7, grey 8, white 9, with gold and silver serving as ×0.1 and ×0.01 multipliers or ±5% and ±10% tolerances. The calculator returns the nominal resistance, the tolerance and the guaranteed value range.Switch to reverse (encode) mode to go the other way: type a target resistance pattern and the tool rounds it to the nearest value

The first two (or three) bands give the significant digits, the next is a ×10ⁿ multiplier and the last is the tolerance. Brown-Black-Red-Gold = 1, 0, ×100, ±5% = 1 kΩ ±5%.

Tolerance is how far the real resistance may stray from the nominal value. A ±5% 1 kΩ resistor can measure anywhere from 950 Ω to 1050 Ω.

QFileDialog
A 4-band resistor has two digit bands; a 5-band adds a third digit for tighter tolerances like ±1%; and a 6-band adds a final temperature-coefficient band showing how much the value drifts per degree. More bands generally means a more precise part.

The bands give a nominal value plus a tolerance window. A ±5% 1 kΩ resistor may legitimately measure anywhere from 950 Ω to 1,050 Ω, and temperature and age can shift it further, so a small mismatch on a multimeter is completely normal.
