E12 (10% tolerance) is the original, coarsest standard and is largely superseded. E24 (5% tolerance) is the modern standard printed on most off-the-shelf resistors today. E96 (1% tolerance) is used in precision instrumentation, metrology, and other tight-tolerance applications. Base values shown are per decade per IEC 60063 and repeat at every power of ten.
The ohm is the SI unit of electrical resistance. One ohm is the resistance between two points of a conductor when a constant potential difference of one volt across those points produces a current of one ampere. Since 2019 it has also been defined in terms of the quantum Hall effect and fundamental physical constants.
Resistance units are powers of ten apart. To convert kilohms to ohms, multiply by 1,000. To convert kilohms to megohms, divide by 1,000. This converter performs that conversion — and every other supported unit — automatically from a single entered value.
There is no numerical difference — one ohm is defined as exactly one volt per ampere. V/A is simply the derived-unit form of the ohm written out in its base SI units of voltage divided by current.
Abohm and statohm are legacy CGS units of resistance, largely replaced by the SI ohm. An abohm equals one nanoohm and belongs to the electromagnetic (EMU) system. A statohm equals roughly 8.9876 × 10¹¹ ohms and belongs to the electrostatic (ESU) system. They occasionally appear in older physics texts and specialized metrology work.
No. This tool only converts a resistance value between units of scale, such as ohms to kilohms. The Ohm's Law Calculator solves for voltage, current, resistance, or power in a circuit when any two of those values are known.
Disclaimer: Results produced by this converter are for reference and educational purposes only and are not a substitute for measuring actual circuit resistance with a properly rated meter. Conversion values assume ideal unit definitions and do not account for measurement tolerance, instrument accuracy, or real-world circuit conditions. All values must be independently verified before use in any circuit design, repair, or component substitution, and any electrical work must comply with applicable codes (NEC / AHJ) and be performed or reviewed by a licensed electrician where required.
