Convert Kilohertz to Terahertz (kHz to THz)
1 kilohertz (kHz) = 1 × 10⁻⁹ terahertz (THz). 1 THz = 1000000000 kHz. Example: 15 kHz = 15 × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ THz.

How to Convert Kilohertz to Terahertz
- 1 kHz = 1 × 10⁻⁹ THz
- 1 THz = 1000000000 kHz
- Example: convert 15 kHz to THz: 15 kHz = 15 × 1 × 10⁻⁹ THz = 1.5 × 10⁻⁸ THz
Formula
THz = kHz ÷ 1000000000
Derivation from SI units:
- 1 kHz = 10³ Hz.
- 1 THz = 10¹² Hz.
- 1 kHz = 1000 Hz ÷ 1000000000000 Hz per THz = 1 × 10⁻⁹ THz
Both units are defined exactly, so the factor is exact. Kilohertz definition: kilohertz; Terahertz definition: terahertz.
Worked examples
- A reading of 16 kHz converts to 1.6 × 10⁻⁸ THz.
16 kHz × 1 × 10⁻⁹ = 1.6 × 10⁻⁸ THz - A value of 48 kHz is 4.8 × 10⁻⁸ THz.
48 kHz × 1 × 10⁻⁹ = 4.8 × 10⁻⁸ THz

Where it's used
Kilohertz are used for audio sample rates, while terahertz appear in optical communications. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many terahertz are in 1 kilohertz?
1 kHz = 1 × 10⁻⁹ THz.
How do I convert kilohertz to terahertz?
Multiply the value in kHz by 1 × 10⁻⁹, or divide it by 1000000000. For example, 15 kHz × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ THz.
Is the kHz to THz conversion exact?
Yes. Both units are defined exactly, and 1 kHz is exactly 1 × 10⁻⁹ THz.
