1 cps = 1 Hz = 1 cycle per second = 1 complete oscillation per second
1 mHz = 0.001 Hz = 1/1000 Hz = 1 cycle per 1,000 seconds ≈ 1 cycle per 16.67 minutes
Millihertz in Context
Understanding extremely slow oscillations:
- 1 Hz = 1 cycle per second (normal audio)
- 0.1 Hz = 1 cycle per 10 seconds (slow swing)
- 0.01 Hz = 1 cycle per 100 seconds (very slow)
- 0.001 Hz (1 mHz) = 1 cycle per 1,000 seconds (ultra-rare)
- Relationship: 1 mHz × 1,000 = 1 Hz
Note: The Cycles per Second is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Millihertz belongs to the imperial/US customary system.
History of the Cycles per Second and Millihertz
Before 1960: "Cycles per second" was the standard term
- Common abbreviations: c/s, c.p.s., cps, ~/s
1960: Renamed to "hertz" (Hz)
- Honors Heinrich Hertz (1857-1894)
- Adopted at 11th CGPM (General Conference on Weights and Measures)
- Simplified terminology and standardized notation
Why the change?
- Shorter, more convenient
- Honors a pioneering physicist
- Consistent with other SI units named after scientists (ampere, watt, volt, etc.)
- International standardization
Common Uses and Applications: cps vs millihertz
Explore the typical applications for both Cycles per Second (imperial/US) and Millihertz (imperial/US) to understand their common contexts.
Common Uses for cps
(Historical & Current)
Historical Technical Documents: Pre-1960 radio, electronics, and acoustics literature - understanding older specs. Some Fields Still Use "cycles": Audio engineering may say "cycles" colloquially. Education: Teaching frequency concepts before introducing Hz notation. Older Equipment: Vintage test equipment labeled in cps. Legacy Systems: Industrial control systems that predate 1960 standardization.
When to Use millihertz
Seismology: Ultra-low frequency seismic waves and Earth oscillations (0.3-10 mHz) - critical for understanding deep Earth structure. Geophysics: Tidal deformations, Earth's free oscillations after major earthquakes, core-mantle interaction. Astronomy: Stellar oscillations, Sun's vibration modes, solar physics. Oceanography: Ultra-long period ocean waves, tsunami frequencies, global tidal analysis.
