About Resistance Units

Resistance is measured in ohms (Ω) and sets how much a component opposes the flow of current.

Resistor values run from milliohms (current-shunt sense resistors) up to megaohms and gigaohms (pull-ups and input bias networks). A "10k" resistor is 10,000 Ω — reading the prefix correctly is the difference between a working bias network and a dead one.

Example conversions

  • 4.7 kΩ = 4700 Ω — a common pull-up resistor.
  • 2.2 MΩ = 2,200,000 Ω — a high-impedance bias resistor.

Frequently asked questions
