Resistance Converter

Convert between ohms, milliohms, kilohms and megohms.

Resistor values span a huge range, from the milliohms of a shunt to the megohms of a pull-up, and datasheets and schematics freely mix ohms, kilohms and megohms. Reading a 4.7 kΩ part against a 470 Ω one, or checking a multimeter's megohm reading, means converting between prefixes constantly.

This converter translates any resistance between milliohms, ohms, kilohms and megohms instantly, so component values, measurements and calculations all speak the same unit.
