Electrical Resistance Converter

Convert an electrical resistance among microohms, milliohms, ohms, kiloohms, megaohms, and gigaohms with case-aware symbols.

Reviewed reference factorsValues stay in this browser tabPrefix conversion only; voltage, current, power, impedance, temperature coefficient, tolerance, and safety are not calculated.

Conversion input

Convert a stated electrical resistance

Enter the resistance reported by a meter, component marking, drawing, or calculation and select the exact SI prefix.

Find a unit6 / 6

Filter by unit name, symbol, or code. Your current selections remain available.

Known value0 / 80

Enter a non-negative resistance magnitude and retain measurement frequency, temperature, method, and tolerance separately.

Convert from

Choose the unit attached to the value you entered.

Convert to

Choose the unit required for your report, estimate, or comparison.

Displayed precision

Choose the maximum decimal places shown. This does not increase source accuracy.

Conversion runs locally after the active reference catalogue loads.

What this tool delivers

Electrical Resistance conversion contract

This page rescales an existing resistance and does not apply Ohm's law or treat frequency-dependent impedance as pure resistance.

What it converts

Converts six decimal ohm-prefix units through the coherent SI ohm.

What you provide

A known resistance, exact prefix, destination unit, measurement context, and appropriate precision.

What you receive

A selected equivalent, visible prefix factor, complete comparison table, and CSV file.

Calculation method

How decimal prefixes scale the ohm

The source value is multiplied by its decimal ohm prefix factor and divided by the destination factor. Micro, milli, kilo, mega, and giga mean powers of ten; symbol case remains visible to distinguish milliohm from megaohm.

Quick answers

Electrical Resistance Converter questions

Why does symbol capitalization matter for resistance?

SI prefixes are case-sensitive. Lowercase m denotes milli, or 10^-3, while uppercase M denotes mega, or 10^6. Confusing milliohms and megaohms creates a billion-fold error. This page spells out full unit names alongside symbols, but you should preserve exact capitalization when entering data into another system.

Can this convert impedance to resistance?

No. Impedance can include frequency-dependent reactance as well as resistance and may require a complex magnitude and phase. A numeric value labelled ohms is not enough to identify which quantity it represents. Use an impedance workflow with frequency and circuit context rather than stripping the label and converting prefixes here.

Does converting resistance check a component power rating?

No. Power dissipation depends on circuit voltage or current and operating conditions, while component suitability also involves tolerance, temperature coefficient, pulse behavior, voltage rating, environment, and derating. This converter only changes the resistance unit. Verify the complete electrical and thermal design against the component datasheet.
