The FDA have released a file "Full Prescribing Information" for Rytary:

Table 1 of the file shows the dose of Rytary for people converting from immediate release carbidopa-levodopa.

The relationship between Rytary and levodopa is non-linear. Anyone know why?
But, roughly speaking:
100mg levodopa = 170mg Rytary
