Convert Terahertz to Millihertz

Enter the number of terahertz that you want to convert to millihertz.

1 THz (terahertz) = 1e15 mHz (millihertz)

How to Convert Terahertz to Millihertz

The terahertz and millihertz are both units of frequency. By definition, 1 terahertz equals exactly 1e15 millihertz. This means to convert terahertz to millihertz, you multiply by 1e15.

Formula

millihertz = terahertz × 1e15

Step-by-Step Example

Convert 5 THz to millihertz:

1
Convert 5 THz to millihertz

We need to convert terahertz to millihertz

2
Apply the formula

Since 1 THz = 1e15 mHz, multiply by 1e15

5 × 1e15 = 5e15

Answer

5 THz = 5e15 mHz

About These Units

Terahertz (THz)

A terahertz (THz) equals 1 trillion hertz. Terahertz radiation lies between microwave and infrared. THz imaging penetrates clothing and packaging for security scanning. Used in spectroscopy, medical imaging, and wireless communications research.

Millihertz (mHz)

A millihertz (mHz) equals 0.001 hertz or one cycle per 1,000 seconds. Millihertz measures very slow oscillations: Earth tides, climate cycles, and seismic waves. Heart rate variability analysis uses millihertz frequencies.
