millihertsejä

Millihertsejä is a unit of frequency, representing one-thousandth of a hertz. Hertz (Hz) is the standard unit of frequency in the International System of Units (SI), defined as one cycle per second. Therefore, one millihertz (mHz) is equal to 0.001 Hz, or one cycle every 1000 seconds. This unit is typically used to describe very low frequencies, such as those encountered in certain scientific or engineering applications where events occur over extended periods. For instance, in seismology, millihertz frequencies might be used to analyze extremely slow ground movements. Similarly, in some fields of astrophysics or geophysics, phenomena occurring over minutes or hours might be expressed in millihertz. While hertz is the most common unit for everyday frequencies like radio waves or sound, millihertz provides a convenient way to express much slower oscillations or cycles without using very small decimal fractions of a hertz. The abbreviation for millihertz is mHz.
