ConvBolt — Unit ConverterTablespoons to US cups Converter
Converting tablespoons to US cups is a multiplication by a fixed factor: 1 tbsp = 0.0625 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 tablespoon works out to 0.0625 cup, the us cup is the much smaller unit of the two: a figure given in us cup always carries a smaller number than the same measurement in tablespoon. A chart drawn in tbsp can hide that, so check which label the axis uses before you compare two readings.
When a container size is certified in US cups but you are dosing in tablespoons, it pays to convert from the certified figure rather than from a rounded label.
The conversion factor used here is 0.0625 cup per tablespoon (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 tbsp a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 16 tbsp per cup, the exact reciprocal, so a round trip through both pages returns your original number.
