# Sinusoidal Vibration Calculator (Info)

Use the online vibration calculator to convert amplitudes of sinusoidal vibration between different unit systems, physical variables and overall amplitude values.

### Features

The calculator handles displacement, velocity and acceleration units commonly used in mechanical vibration analysis:

- Vibration in mil, µm, ips (in/s), mm/s, ft/s², m/s², g
- Peak (pk), peak to peak (pk-pk) or rms amplitude
- Vibration frequency in Hz, cpm or rad/s
- Converts phase shift measurements
- Solve for the frequency at which two different vibration quantities are equal

Also available in the chrome web store:

### Directions for use

With the "solve for frequency" box **unchecked**: the calculator will convert the entered vibration amplitude (and phase angle) to the other physical variables and units, at the given frequency:

- Set the vibration frequency (Hz or CPM, only one), press 'Enter'.
- Set the vibration amplitude (only one), press 'Enter'.
- Optionally, set the vibration angle (only one), press 'Enter'.

With the "solve for frequency" box **checked**: the calculator will find the frequency at which the vibration amplitude corresponds to two given vibration amplitude values:

- Set a vibration amplitude, press 'Enter'.
- Set vibration amplitude of another physical variable, press 'Enter'.
