Millihertz (mHz) - Definition and Overview

What is Millihertz?

Millihertz is a measure of frequency equal to one by thousandth(1/1000) of a cycle per second. Millihertz can be abbreviated as mHZ.

Summary

  • Millihertz (mHz) is a unit of frequency in the International System of Units (SI) equal to one thousandth of a hertz (1 mHz = 10^-3 Hz)
  • It is used to measure low frequencies, commonly in applications such as biological rhythms and certain types of electronic signals.

Hertz (Hz) - Definition and Overview

What is Hertz?

Hertz is defined as the frequency equalling one cycle per second. The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as Hz.

Summary

  • Hertz (Hz) is the standard unit of frequency in the International System of Units (SI), defined as one cycle per second
  • It is widely used across various fields including physics, engineering, and music to measure the frequency of periodic phenomena such as sound waves, electromagnetic waves, and mechanical vibrations.

How to Convert Millihertz to Hertz?

1 Millihertz is equal to 0.001 Hertz. To convert Millihertz to Hertz, use this simple formula:

Hertz = Millihertz x 0.001

So, just multiply the number of Millihertz by 0.001 to get equivalent value in Hertz.

Example 1:

Convert 5 Millihertz to Hertz
5 x 0.001 = 0.005 Hertz

Example 2:

Convert 7.5 Millihertz to Hertz
7.5 x 0.001 = 0.0075 Hertz
