You can put this solution on YOUR website! Set up an equation with both units.
Then divide (depending on which conversion factor you want)
Example:
8 yits = 75 plops
.
.
.
8 nits/75 plops
(8/75) nits/plops(conversion factor from plops to nits)
or
75 plops/8 nits
(75/8) plops/nits (conversion factor from nits to plops)
