Feet to Inches Converter

Converting feet to inches is a multiplication by a fixed factor: 1 ft = 12 in. The table below covers the values people look up most often, and the formula section shows exactly where that factor comes from.

Because one foot works out to 12 in, the inch is the noticeably larger unit of the two: a figure given in inch always carries a larger number than the same measurement in foot. A chart drawn in ft can hide that, so check which label the axis uses before you compare two readings.

DIY and home-improvement work is where this pair shows up most: you measure in feet but the hardware store or an imported product sheet quotes inches, so the conversion has to be right the first time.

The conversion factor used here is 12 in per foot (0 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 ft a factor rounded to three decimals can be off by a measurable amount. The reverse direction uses 0.08333333 ft per in, the exact reciprocal, so a round trip through both pages returns your original number.
