--------------------------------------------------------------------------------
I am wanting to compute arm resonances for various carts/arm combos.
The cartridge database (www.cartridgedb.com) works only w/cm/dyne.
One cart is 28um/mN, another 30. People say go by tracking force; my Yamaha MC705 calls for 1.7g, but has a compliance of 6.0x10(-6)cm/dyne, a very low compliance, whereas my B&O MMC1 is 1g/very high compliance. Sure would help to have empirical data and plug it into the calculator

1 dyne/cm = 0.000001 millinewton/micrometer
This is the correct place for dyne /centimeter to millinewton / micrometer force conversions
Convert 14 Dyne/Centimeter to Millinewton/Micrometer

BTW that's not SI, you are only allowed one multiplier (excluding the annoying kg exception), so that should be 28mm/N - SI is pretty strict about syntax to avoid ambiguity and multiple representations of the same thing(*)
You can read up on this here - well worth it if you are new to or unsure about SI
International System of Units - Wikipedia
BTW the dyne is not SI, its from the cgs system which is all but obsolete (textbooks tend to prolong the death-throes of such things)
(*) Don't get me started on the crazy baroque imperialisms like torque being measured in both inch-ounces and foot-pounds
