Type of plywood for kitchen floor

[Mr Fizzion]

I am going to replace a section of the kitchen floor with plywood (the floorboards are quite badly damaged) and I'm a bit confused as to the different types available.

I know that WBP = water and boilproof, but what is the difference between marine grade and exterior grade?

Would birch plywood be suitable for flooring?

TIA

Exterior is WBP - marine is much more expensive and you probably don't need it unless you're making a boat.

If it's WBP :-)

wouldnt it look better to use floorboards?

If they were exposed then yes. They will be covered with vinyl and then when I get round to replacing all the cupboards I will probably use ceramic tiles.

then why the extra expense of ply?
