About Converting Terahertz to Gigahertz
Terahertz and Gigahertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Terahertz is 1000000000000 hertz units, and gigahertz is 1000000000 hertz units.
Formula
gigahertz = terahertz × 1000
This factor comes from each unit's defined relationship to the category's base unit: 1 terahertz equals 1e+12 base units, and 1 gigahertz equals 1000000000 base units, so dividing one by the other gives the direct terahertz-to-gigahertz factor of 1000.
Simple example
1 THz × 1000 = 1,000 GHz
1 terahertz = 1,000 gigahertz.
Real-world example
1,000 THz × 1000 = 1,000,000 GHz
1,000 terahertz = 1,000,000 gigahertz.

Frequently asked questions
How many gigahertz are in 1 terahertz?
1 terahertz equals 1,000 gigahertz, using the exact defined conversion factor rather than an estimate.
How do I convert terahertz to gigahertz?
Multiply the terahertz value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert gigahertz back to terahertz?
Use the reverse factor: 1 gigahertz equals 0.001 terahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a terahertz?
Terahertz (THz) is a unit of frequency.
What is a gigahertz?
Gigahertz (GHz) is a unit of frequency.
Is the terahertz to gigahertz conversion exact?
Yes. Both terahertz and gigahertz 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.
