How do youconvert milliliters to ounces?
Wikipedia provides this information: 1 US fluid ounce = 29.5735297 milliliters (about 30 mL) so your conversion for ounces would be using '30"(millileters) x the number of ounces you want to convert. Therefore; 2 ounces would equal 60 millileters. Or you could get real fancy and use the long string of nuumbers x the number of ounces you want to convert - then you'd have a real mess if you were adding the liquid to a batter. Truth is, there isn't any real conversion for the metric system into the US measuring system. It always comes out with a left-over digits. So, the easiest and less frustrating thing to do is to round-up the number. Hence 30 and pray. I think Europe should have converted to our system, at least we have a measurment system based on equal segments that can be multiplied, divided or added to produce a whole number.
Ounces do not convert into milliliters. Ounces are weight and milliliters are volume. Milliliters are usually for measuring liquid and each individual liquid will have a different weight per milliliters. So you can't convert generally, you need to know the name of the substance that you are measuring. If you are talking about fluid ounces, then 300 milliliters is 10.144 fluid ounces.
