Terahertz to gigahertz Conversion
1 terahertz (THz) is equal to 1000 gigahertz (GHz).
1 THz = 1000 GHz
or
1 GHz = 0.001 THz
Formula
To convert a frequency & wavelength from terahertz (THz) to gigahertz (GHz), multiply the frequency & wavelength in terahertz by 1000
f(GHz) = f(THz) × 1000
Examples:
Convert 250 terahertz to gigahertz:
f(GHz) = 250THz × 1000 = 250000 GHz

Frequently asked questions
How do I convert terahertz to gigahertz?
Multiply the value in terahertz by 1000 to get the result in gigahertz. For example, 5 THz × 1000 = 5000 GHz.
How many gigahertz are in 1 terahertz?
1 terahertz (THz) is equal to 1000 gigahertz (GHz).
How do I convert gigahertz back to terahertz?
Use the inverse operation: divide the value in gigahertz by 1000 to get the result in terahertz.
How accurate is the terahertz to gigahertz conversion?
The converter multiplies by the conversion factor 1000 and rounds the result to 9 decimal places by default. You can increase or reduce the precision with the digits option on this page.
