73 calculators online
  New calculla released ! Please go to calculla.com for the calculla v2. It's better, faster, more beautiful, redone for you in most modern technologies.
  Two cars related tables released today: Tire codes - speed ratings and Tire codes - load index
  This time 3 new calculators for fractions: Fractions: adding and subtracting, Fractions: 4 operations and Fractions: inverse (reciprocal). Each of them shows all sub-steps needed to compute common denominators, create improper fraction (if needed), reduce the fraction etc.

Resistors color codes
Calculator decodes parameters of resistor (resistance value, tolerance, temperature coefficient) painted as colored bands on resistor and vice versa.
How to use this tool

  • If you have unknown resistor read color pattern from it and put it to color table below (by clicking on cells). You get decoded resistor's parameters (resistance value, tolerance and - when you're using six strips pattern - temperature coefficent) in the result table on the bottom of the page.
  • If you know resistor's parameter and want to encode them into color strips pattern choose needed parameters in form below color table (resistance value, tolerance and temperature coefficent). Next, you will read colors pattern from schematic resistor's image or from color table (colors used in patterns are bordered).
