The are two different systems of measurement customary and metric, but ml is more accurate because of smaller increments
30ml is equivalent to 1 US fluid ounce (1.014 to be more exact).
2 fluid ounces is 59.1 (59.1471) mL
10 mL is equal to about 0.338 fluid ounces.
90 mL equates to approximately 3.04 fluid ounces.
10 US fluid ounces = 295.735 ml
256 mL is about 8.656 US fluid ounces.
238 mL = 8 fluid ounces.
Actually 1 ounce contains 29.57 milliliters so 6 ounces has about 177.44 ml. Is that a US fluid ounce or an Imperial fluid ounce? They're not the same volume, and you'll only get an approximation. Either fluid ounce is around 30 ml. So 6 ounces is about 180 ml. Ounces is measured to 1 significant figure - it's not 6.000 ounces, for example. For this reason, 180 ml is accurate enough.
12 US fluid ounces = 354.88 ml 12 Imperial fluid ounces = 340.96 ml
About 50.3 mL in 1.7 fluid ounces.
8 US fluid ounces = about 236.6 mL.
750 milliliters = 25.3605169 US fluid ounces
