Rings to buy

Hello, the question is that I am going to buy the rings of my Celebrety Century, in Venezuela we talk about measures of how the last thing is 0.60 and my car is already 0.60
searching in Amazon discovered that in the United States they use another measure for example the largest ring is 1.50 mm Seaed Power E-432K 1.50mm 1.50mm Premium Piston
there is a way of being able to know if you can know if you can know if you 1.50 mm is the same 0.60 for us?
Excuse me but I really don't know where to go and ask for help
