One US fluid ounce is 29.57 mL, so to turn milliliters into fluid ounces divide by 29.57. For a quick estimate, 30 mL is about 1 fl oz, 100 mL about 3.4 fl oz and 500 mL about 17 fl oz. The charts below go both ways and link to a full page for the bottle and recipe sizes people ask about most.
These are US fluid ounces, the ones on US drink labels and measuring cups. A UK fluid ounce is slightly smaller, 28.41 mL, so the same bottle shows a slightly higher number of UK fluid ounces. Neither has anything to do with the ounces on a kitchen scale, which measure weight; for those, see grams in an ounce.

Measuring mL with US tools
Most liquid measuring cups print mL on one side, which is the simplest way to measure. With spoons only, 1 Tbsp is 14.79 mL and 1 tsp is 4.93 mL, so 15 mL is a tablespoon and 5 mL a teaspoon for any practical purpose. For larger amounts, mL to cups gives the nearest cup and spoon combination.
