About Converting Gigaohms to Teraohms
Gigaohm 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: Gigaohm is 1000000000 ohm units, and teraohm is 1000000000000 ohm units.
Formula
teraohms = gigaohms × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 gigaohm equals 1000000000 base units, and 1 teraohm equals 1e+12 base units, so dividing one by the other gives the direct gigaohm-to-teraohm factor of 0.001.
Simple example
1 GOhm × 0.001 = 0.001 TOhm
1 gigaohm = 0.001 teraohms.
Real-world example
120 GOhm × 0.001 = 0.12 TOhm
120 gigaohms = 0.12 teraohms.

Reverse conversion: Teraohm to Gigaohm
0.001 TOhm × 1000 = 1 GOhm
0.001 teraohms = 1 gigaohm.
gigaohms = teraohms × 1000

Frequently asked questions
How many teraohms are in 1 gigaohm?
1 gigaohm equals 0.001 teraohms, using the exact defined conversion factor rather than an estimate.
How do I convert gigaohm to teraohm?
Multiply the gigaohm value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert teraohm back to gigaohm?
Use the reverse factor: 1 teraohm equals 1,000 gigaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigaohm?
Gigaohm (GOhm) is a unit of electricity.
What is a teraohm?
Teraohm (TOhm) is a unit of electricity.
Is the gigaohm to teraohm conversion exact?
Yes. Both gigaohm and teraohm are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
