MC cartridge output measurements

Can someone tell me what is the conversion ratio from the JVC 3.54cm/sec standard to the CBS 5.0cm/sec standard. In other words, if a cartridge output is measured at .3mv using the JVC standard, what would be this cartridge output using the more common CBS measurement standard. Benz and Zyx are using the JVC standard to measure their cartridge output while most other (if not all) cartridge manufacturers use the CBS standard. Thank You. Sly

ARmstrod is correct if output in mV has a linear relationship to velocity in cm/sec and if any constants in the equation are equal to 1.0, which is probably essentially true, in this range of velocity at least.

I have the sneaking suspicion that most manufacturers now adhere to the 5 cm/sec standard, since that makes it appear that their cartridges have a higher output compared to ones with rated output based on velocity of 3.54 cm/sec. I don't even know where the 5 cm/sec standard came from or why it was introduced at all, since in the good old days everyone used the lower velocity as standard for rating cartridge output (at least to the best of my knowledge). It's kind of like turning the volume up to 11, a distinction without a difference.
