About Millimetres per second squared
The millimetre per second squared (mm/s²) equals 10⁻³ m/s², the standard unit for vibration acceleration in machine condition monitoring. ISO 10816 and ISO 20816 define machinery vibration limits in mm/s and mm/s²; ISO 10816-3 Zone A boundary for industrial machinery is ≈32 mm/s² at 2.2 Hz. Seismically, MMI VI ground shaking (masonry damage threshold) corresponds to 620-1250 mm/s² peak ground acceleration. 1 mm/s² = 10⁻³ m/s² ≈ 1.02 × 10⁻⁴ g₀.
About Centimetres per second squared
The centimetre per second squared (cm/s²) is the CGS coherent unit of acceleration, numerically identical to the Gal (1 cm/s² = 1 Gal = 0.01 m/s²). In the CGS system, Newton's second law reads F [dyn] = m [g] × a [cm/s²]. Strong-motion seismology records earthquake accelerograms in cm/s²: the 1940 El Centro earthquake reached a peak ground acceleration of 341 cm/s² ≈ 0.35 g₀. Japan's JMA shindo 7 (structural collapse) threshold is above 400 cm/s². 1 cm/s² = 0.01 m/s² = 1 Gal ≈ 1.02 × 10⁻³ g₀.
