Liters to US cups Converter

Converting liters to US cups is a multiplication by a fixed factor: 1 L = 4.226753 cup. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.

Because one liter works out to 4.226753 cup, the us cup is the larger unit of the two: a figure given in us cup always carries a larger number than the same measurement in liter. A chart drawn in L can hide that, so check which label the axis uses before you compare two readings.

Kitchen and workshop measuring are where this pair comes up: a jug marked in liters alongside a recipe or container printed in US cups is the classic case, and it is why the two labels rarely agree to the eye.

The conversion factor used here is 4.226753 cup per liter (6 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 L a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 0.2365882 L per cup, the exact reciprocal, so a round trip through both pages returns your original number.
