millihertz [mHz] to terahertz [THz] Converter

Quick Reference

1 millihertz (mHz) = 1.0000e-15 terahertz (THz)

1 terahertz (THz) = 1.0000e+15 millihertz (mHz)

How to Convert millihertz to terahertz

1 mHz = 1e-15 THz
1 THz = 1000000000000000 mHz

To convert millihertz to terahertz, divide the value by 1.0000e+15 (equivalently, multiply by 1.0000e-15). To convert terahertz back to millihertz, multiply by 1.0000e+15.

Example: convert 10 mHz to THz:
10 mHz = 10 x 1e-15 = 1.0000000000000002e-14 THz

↔ Convert terahertz to millihertz

millihertz

Definition: A millihertz (mHz) is a unit of frequency equal to one thousandth (1/1000) of a hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The millihertz is derived from the hertz, named after the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves. The prefix 'milli-' denotes a factor of 10-3, adhering to the SI system of units.

Current use: Millihertz is used to measure very low frequencies, often encountered in fields like geophysics (e.g., measuring seismic waves), biology (e.g., measuring slow biological rhythms), and some areas of electronics and signal processing where extremely slow oscillations or events are analyzed.

terahertz

Definition: A terahertz (symbol: THz) is a unit of frequency equal to one trillion (1,000,000,000,000) hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The terahertz is derived from the hertz, named after the German physicist Heinrich Hertz. The prefix 'tera-' denotes a factor of 1012, adhering to the SI system of units.

Current use: Terahertz radiation, or T-rays, is used in emerging technologies such as medical imaging, security screening, and materials science. Terahertz frequencies fill the gap between microwaves and infrared light, offering unique capabilities in sensing and spectroscopy, although widespread applications are still under development.
