Resistance Converter
Enter a resistance value and review equivalent values across common SI ohm prefixes.
A QUICK WALKTHROUGH
How to use this tool
- Enter a finite resistance value.
- Choose the input ohm prefix.
- Review equivalent values in every supported unit.
SI resistance prefixes
The converter uses ohms as the base unit and supports nΩ, µΩ, mΩ, Ω, kΩ, MΩ, GΩ, and TΩ. Each prefix is an exact power-of-ten scale.
Finite values and precision
Inputs accept decimal and scientific notation, reject non-finite or malformed values, and display about 12 significant digits. Extremely large results that overflow are rejected.
Local calculation
Values are validated and converted in your browser. Nothing is uploaded or stored.
GOOD TO KNOW
Common questions
Which resistance units are supported?
Nanoohms, microohms, milliohms, ohms, kilohms, megohms, gigohms, and teraohms.
How are the conversions calculated?
The input is converted to ohms using its SI prefix, then divided by each target unit factor.
Can I enter scientific notation?
Yes. Values such as 1.2e6 are accepted, provided the resulting value remains finite.
