Rendered to 6 significant figures.
Formula
Formula
THz = kHz × 1e-9
Multiply any value in kilohertz by 1e-9 to obtain the value in terahertz.
Worked example
Convert 1e+9 kHz to THz.
- 01Start with 1e+9 kHz.
- 02Multiply by the conversion factor: 1e+9 × 1e-9 = 1 THz.
Result1e+9 kHz = 1 THz

FAQ
What is the conversion factor from kHz to THz?
1 kHz equals 1e-9 THz. To convert, multiply the value in kilohertz by 1e-9.
How do I convert 1 kHz to THz?
1 kHz = 1e-9 THz. For any value, multiply by 1e-9.
How do I convert THz back to kHz?
Divide by the same factor — or equivalently, multiply by 1e+9. So 1 THz = 1e+9 kHz.
When would I need to convert kilohertz to terahertz?
Frequency conversions between kHz and THz are needed in signal and RF engineering, motor and turbomachinery rotational-speed work, vibration and pulse-rate analysis, and control-loop sample-rate specification. Hz dominates electronics and instrumentation; kHz, MHz and GHz cover audio through microwave; rpm and rps dominate mechanical rotational equipment; cycles per minute, second and hour cover slow industrial cyclic processes. Angular frequency (rad/s) and time-period (Hz ↔ seconds) conversions are NOT included — they require either a 2π factor or a reciprocal relationship.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
