About Converting Teraohms to Gigaohms
Teraohm and Gigaohm 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: Teraohm is 1000000000000 ohm units, and gigaohm is 1000000000 ohm units.
Formula
gigaohms = teraohms × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 teraohm equals 1e+12 base units, and 1 gigaohm equals 1000000000 base units, so dividing one by the other gives the direct teraohm-to-gigaohm factor of 1000.
Simple example
1 TOhm × 1000 = 1,000 GOhm
1 teraohm = 1,000 gigaohms.
Real-world example
120 TOhm × 1000 = 120,000 GOhm
120 teraohms = 120,000 gigaohms.

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

Frequently asked questions
How many gigaohms are in 1 teraohm?
1 teraohm equals 1,000 gigaohms, using the exact defined conversion factor rather than an estimate.
How do I convert teraohm to gigaohm?
Multiply the teraohm value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert gigaohm back to teraohm?
Use the reverse factor: 1 gigaohm equals 0.001 teraohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a teraohm?
Teraohm (TOhm) is a unit of electricity.
What is a gigaohm?
Gigaohm (GOhm) is a unit of electricity.
Is the teraohm to gigaohm conversion exact?
Yes. Both teraohm and gigaohm are defined by fixed standards rather than physical artifacts, so the factor of 1000 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.
