Fluid ounces to Liters Converter

Converting fluid ounces to liters is a multiplication by a fixed factor: 1 fl oz = 0.02957353 L. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.

Because one fluid ounce works out to 0.02957353 L, the liter is the far smaller unit of the two: a figure given in liter always carries a smaller number than the same measurement in fluid ounce. A chart drawn in fl oz can hide that, so check which label the axis uses before you compare two readings.

When a container size is certified in liters but you are dosing in fluid ounces, it pays to convert from the certified figure rather than from a rounded label.

The conversion factor used here is 0.02957353 L per fluid ounce (8 significant digits as shown). Kept to seven figures it covers professional measurement; if you round it to two or three decimals for a spreadsheet, the error scales with the input — at a value of 1,000 fl oz a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 33.81402 fl oz per L, the exact reciprocal, so a round trip through both pages returns your original number.
