Read the feet-and-inches result alongside the total inches, decimal feet, centimeters, and meters. A length \u00f7 length operation shows a unitless ratio instead.<\/li>\n<\/ol>\n<h2>Understanding feet, inches, and length ratios<\/h2>\n<p>A foot contains 12 inches, so feet-and-inches measurements do not behave like decimal numbers. For example, 5 ft 8 in is \\(5+8\/12\\) feet, not 5.8 feet. Expressing both measurements in total inches before calculating avoids that common mistake. The calculator then carries each full group of 12 inches into feet when it formats the result.<\/p>\n<p>The <strong>Inch fraction<\/strong> field lets you enter a measurement in sixteenths of an inch, including familiar values such as 1\/2, 1\/4, and 3\/4 inch. This is useful when adding cut lengths, finding the difference between two dimensions, or scaling a measurement. Subtraction can produce a negative length, which indicates how far length A falls below length B.<\/p>\n<p>Multiplying a length by a number scales it; dividing by a number splits or reduces it. Dividing length A by length B answers a different question: how many times as long is A as B? Because both measurements are converted to inches before division, their units cancel. A ratio of 2 means A is twice as long as B; it is not a result of 2 inches or 2 feet.<\/p>\n<p>The conversion tab also accepts decimal feet or centimeters directly. Decimal feet may be convenient for calculations, while feet and fractional inches are often easier to mark on a tape measure. For a separate metric-to-imperial conversion, see the <a href=\"https:\/\/wpcalc.com\/en\/converters\/meters-to-feet\/\">meters to feet converter<\/a>.<\/p>\n<h2>Precision and practical limits<\/h2>\n<p><strong>Display fraction precision<\/strong> changes only the feet-and-inches display. If an exact calculation lands between the available marks, that display rounds to the nearest selected fraction; total inches, decimal feet, centimeters, and meters retain the calculated value. They may therefore appear slightly different from a conversion made using the rounded feet-and-inches display. Choosing 1\/16 inch gives a finer display than choosing 1\/2 inch, but it does not make the original measurement more accurate.<\/p>\n<p>Enter non-negative whole numbers in the <strong>Feet<\/strong> and <strong>Whole inches<\/strong> fields. You can enter 12 or more whole inches; the result automatically carries them into feet. A divisor cannot be zero, and length B must be greater than zero when calculating a ratio. The calculator limits entered lengths and the magnitude of length results to one billion inches.<\/p>\n<p>Unit conversion does not account for measurement tolerance, saw-kerf loss, or rounding required by a particular project. Check those separately before cutting or ordering materials. If you are turning drawing measurements into real-world lengths, a <a href=\"https:\/\/wpcalc.com\/en\/converters\/map-scale-calculator\/\">map scale calculator<\/a> may also help; for standardized sheet dimensions, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/paper-size-converter\/\">paper size converter<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Add, subtract, multiply, or divide lengths in feet and fractional inches, or convert decimal feet or centimeters.
