How to split utilities

[Mauricio Salom]

I have a single family home with a garage conversion. Both are 2bed 1 bath. Iam moving out and I am going to rent both units. I have not lived in the property while the other unit was occupied so I dont have any numbers to find the average so I'm looking for a good/fair way to split the utilities between both tenants. Anyone with a similar property please let me know how you are splitting things thanks.
