ConvBolt — Unit ConverterUS cups to Milliliters Converter
Converting US cups to milliliters is a multiplication by a fixed factor: 1 cup = 236.5882 ml. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.
Because one us cup works out to 236.5882 ml, the milliliter is the far larger unit of the two: a figure given in milliliter always carries a larger number than the same measurement in us cup. A chart drawn in cup 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 US cups alongside a recipe or container printed in milliliters is the classic case, and it is why the two labels rarely agree to the eye.
The conversion factor used here is 236.5882 ml per us cup (4 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 cup a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 0.004226753 cup per ml, the exact reciprocal, so a round trip through both pages returns your original number.
