1. What is THz to Hz Conversion?

The THz to Hz conversion is a simple unit conversion between terahertz (THz) and hertz (Hz), the standard unit of frequency in the International System of Units (SI). 1 THz equals 10¹² Hz.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Hz \) — Frequency in hertz
• \( THz \) — Frequency in terahertz
• \( 10^{12} \) — Conversion factor (1 THz = 1,000,000,000,000 Hz)

Explanation: The formula simply multiplies the terahertz value by 10¹² to convert to hertz, since "tera" represents the 10¹² prefix in the metric system.

3. Importance of Frequency Conversion

Details: Accurate frequency conversion is essential in fields like telecommunications, radio astronomy, spectroscopy, and electronics where different frequency ranges are used for different applications.

4. Using the Calculator

Tips: Enter the frequency value in terahertz (THz). The calculator will automatically convert it to hertz (Hz). Only positive numbers are valid inputs.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between THz and Hz?
A: THz (terahertz) is a unit of frequency equal to 10¹² Hz (hertz). Hertz is the base unit, while terahertz represents a much higher frequency range.

Q2: What are common applications of THz frequencies?
A: Terahertz radiation is used in medical imaging, security scanning, materials science, and telecommunications research.

Q3: How precise is this conversion?
A: The conversion is mathematically exact since it's based on the metric prefix definition.

Q4: Can I convert Hz back to THz?
A: Yes, simply divide the Hz value by 10¹² to get THz.

Q5: What comes after THz in the frequency scale?
A: After THz comes PHz (petahertz, 10¹⁵ Hz), then EHz (exahertz, 10¹⁸ Hz).
