Hectohertz (hHz) - Definition and Overview

What is Hectohertz?

Decahertz is a measure of frequency equal to hundred cycles per second. Decahertz can be abbreviated as daHZ.

Summary

  • Hectohertz (hHz) is a unit of frequency in the International System of Units (SI) equal to one hundred hertz (1 hHz = 100 Hz)
  • It is used to measure frequencies that are higher than those typically measured in decahertz but lower than those measured in kilohertz.

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.

How to Convert Hectohertz to Millihertz?

1 Hectohertz is equal to 100000 Millihertz. To convert Hectohertz to Millihertz, use this simple formula:

Millihertz = Hectohertz x 100000

So, just multiply the number of Hectohertz by 100000 to get equivalent value in Millihertz.

Example 1:

Convert 5 Hectohertz to Millihertz
5 x 100000 = 500000 Millihertz

Example 2:

Convert 7.5 Hectohertz to Millihertz
7.5 x 100000 = 750000 Millihertz
