Ok, so, for Colombia I tried two methods:
1) BOM gives us a benchmark of 1.5 million dollars that gives a similar amount of films per year as 100 millions DOM. That would give you a multiplier of 66,6. Now, there's a lot of different prices depending on city, day of the week, time of the day, seat, 3D, 4D and a bunch of other stuff but the Ministry of Culture gives us an average price of 9000 pesos. With current ER that would give us a multiplier of 200 admissions to DOM equivalent dollars.
2) The benchmark of 1 million in admissions is usually surpassed by 10 to 15 films, the same ammount for 200 millions DOM. That lines up with method 1.
So, I'd say it would be 66,6 dollars to dollars and 200 admissions to dollars.
