hertz [Hz] to millihertz [mHz] Converter

Quick Reference

1 hertz (Hz) = 1000 millihertz (mHz)

1 millihertz (mHz) = 0.001 hertz (Hz)

How to Convert hertz to millihertz

1 Hz = 1000 mHz
1 mHz = 0.001 Hz

To convert hertz to millihertz, multiply the value by 1000. To convert millihertz back to hertz, divide by 1000.

Example: convert 10 Hz to mHz:
10 Hz = 10 x 1000 = 10000 mHz

↔ Convert millihertz to hertz

hertz

Definition: Hertz (symbol: Hz) is the SI unit of frequency, defined as the number of cycles per second of a periodic phenomenon. One hertz is equivalent to one cycle or event per second.

History/origin: The hertz is named after Heinrich Hertz, a German physicist who proved the existence of electromagnetic waves in the late 19th century. The unit was adopted as a standard unit for frequency in the 20th century.

Current use: Hertz is widely used across various fields to measure frequency, including radio waves, audio signals, computer processing speeds, alternating current (AC) electricity, and any oscillating or repeating phenomenon. It's a fundamental unit in physics, engineering, and technology.

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<sup>-3</sup>, 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.

hertz [Hz] to millihertz [mHz] Converter

What is 1 Hz in mHz?
1 hertz (Hz) equals 1,000 mHz, and 1 mHz equals 0.001 Hz.
How do I convert hertz to millihertz?
Multiply by 1,000: 10 Hz × 1,000 = 10,000 mHz. The converter above does it for any value, with the precision you choose.
What is 100 Hz in mHz?
100 Hz = 100,000 mHz. Common amounts are listed on this page, each with its own step-by-step page.
Is a hertz bigger than a millihertz?
Yes. 1 Hz = 1,000 mHz, so the same quantity becomes a larger number when written in mHz.
