Context values
Some unit families need one extra value for a physically accurate result.
Attoohm is 1e-18 ohm units.
Result = input x 1e-6 / 1e-18.

About Converting Microohms to Attoohms
Microohm and Attoohm both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Microohm is 0.000001 ohm units, and attoohm is 1e-18 ohm units.
Formula
attoohms = microohms × 1000000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 microohm equals 0.000001 base units, and 1 attoohm equals 1e-18 base units, so dividing one by the other gives the direct microohm-to-attoohm factor of 1000000000000.
Simple example
1 uOhm × 1000000000000 = 1,000,000,000,000 aOhm
1 microohm = 1,000,000,000,000 attoohms.
Real-world example
120 uOhm × 1000000000000 = 1.2e+14 aOhm
120 microohms = 1.2e+14 attoohms.

Reverse conversion: Attoohm to Microohm
1 aOhm × 1e-12 = 1e-12 uOhm
1 attoohm = 1e-12 microohms.
microohms = attoohms × 1e-12

Frequently asked questions
How many attoohms are in 1 microohm?
1 microohm equals 1,000,000,000,000 attoohms, using the exact defined conversion factor rather than an estimate.
How do I convert microohm to attoohm?
Multiply the microohm value by 1000000000000. The converter above does this instantly to whatever precision you set.
How do I convert attoohm back to microohm?
Use the reverse factor: 1 attoohm equals 1e-12 microohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a microohm?
Microohm (uOhm) is a unit of electricity.
What is a attoohm?
Attoohm (aOhm) is a unit of electricity.
Is the microohm to attoohm conversion exact?
Yes. Both microohm and attoohm are defined by fixed standards rather than physical artifacts, so the factor of 1000000000000 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
