Vibration amplitude converter (acceleration, velocity, displacement)
Convert between g, mm/s and µm at a given frequency.
Calculating…
How it's calculated
v = a ÷ (2πf)
d = v ÷ (2πf)
RMS = peak × 0.707 (pure sine)
The same vibration looks very different depending on the unit. Displacement highlights low-frequency problems, velocity covers the mid range most used for machine condition (ISO 10816/20816 use mm/s RMS), and acceleration shows high-frequency bearing and gear faults.
These conversions are exact for a single frequency (a pure sine). For a broadband overall reading they are only approximate.
