- Acoustics: The force that will accelerate a 1-gram mass at the rate of 1 cm/sec. The old standard reference level for sound pressure was 0.0002 dyne/sq. cm. The same level today is expressed as 20 micro pascals, or 20 µPa.
- Electronics: The unit of force in the cgs (centimeter-grams-second) system equal to that required to produce, in a 1-gram mass, an acceleration of 1 centimeter per second for every second that the force is applied.
