About Converting Milliohms to Teraohms
Milliohm and Teraohm 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: Milliohm is 0.001 ohm units, and teraohm is 1000000000000 ohm units.
Formula
teraohms = milliohms × 1e-15
This factor comes from each unit's defined relationship to the category's base unit: 1 milliohm equals 0.001 base units, and 1 teraohm equals 1e+12 base units, so dividing one by the other gives the direct milliohm-to-teraohm factor of 1e-15.
Simple example
1 mOhm × 1e-15 = 1e-15 TOhm
1 milliohm = 1e-15 teraohms.
Real-world example
120 mOhm × 1e-15 = 1.2e-13 TOhm
120 milliohms = 1.2e-13 teraohms.

Reverse conversion: Teraohm to Milliohm
1e-15 TOhm × 1e+15 = 1 mOhm
1e-15 teraohms = 1 milliohm.
milliohms = teraohms × 1e+15

Frequently asked questions
How many teraohms are in 1 milliohm?
1 milliohm equals 1e-15 teraohms, using the exact defined conversion factor rather than an estimate.
How do I convert milliohm to teraohm?
Multiply the milliohm value by 1e-15. The converter above does this instantly to whatever precision you set.
How do I convert teraohm back to milliohm?
Use the reverse factor: 1 teraohm equals 1e+15 milliohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliohm?
Milliohm (mOhm) is a unit of electricity.
What is a teraohm?
Teraohm (TOhm) is a unit of electricity.
Is the milliohm to teraohm conversion exact?
Yes. Both milliohm and teraohm are defined by fixed standards rather than physical artifacts, so the factor of 1e-15 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.
