Milliliters to Us Fluid Ounces
A milliliter is one thousandth of a liter, equal to one cubic centimeter, used for medicine doses and small liquid measures. A US fluid ounce is about 29.57 milliliters, used to measure beverages and liquid ingredients in the US. 1 mL equals ≈0.033814 fl oz, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to volume, measured here against volume's base unit (L) — every other volume unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
fl oz = mL × ≈0.033814
mL = fl oz × ≈29.5735
Worked example: 5 mL × ≈0.033814 = ≈0.16907 fl oz.
