calculate?<\/em> dropdown and pick a mode: rectangular box or room, cylinder, sphere, a multi-item box list, or the quick volume converter. Any section you are not using is hidden automatically.<\/li>\n<li>For a <strong>box or room<\/strong>, enter <em>Length (L)<\/em>, <em>Width (W)<\/em> and <em>Height (H)<\/em>, choosing a unit for each (in, ft, yd, cm or m). If a dimension is given as feet plus inches, set the unit to <em>ft<\/em> and type the leftover inches in the <em>+ Inches (with ft)<\/em> field that appears below it.<\/li>\n<li>For a <strong>cylinder<\/strong>, enter <em>Diameter (D)<\/em> and <em>Height (H)<\/em>; for a <strong>sphere<\/strong>, just the diameter. The same feet-plus-inches helper works here too.<\/li>\n<li>For a <strong>move or shipment<\/strong>, choose <em>Multi-item list<\/em> and type one line per box size in the <em>Box list<\/em> field: <code>L W H [qty]<\/code> \u2014 for example <code>24 18 16 2<\/code> means two boxes of 24 \u00d7 18 \u00d7 16. Leave off the quantity for a single box, up to 10 lines. Then set <em>Unit for all list dimensions<\/em> (in, ft, yd, cm or m).<\/li>\n<li>For a plain <strong>unit conversion<\/strong>, choose <em>Quick converter<\/em>, type the <em>Volume<\/em> and its unit (ft\u00b3, in\u00b3, yd\u00b3, m\u00b3, liters or US gallons).<\/li>\n<li>Read the result under <em>Total volume<\/em> in cubic feet, plus instant conversions to in\u00b3, yd\u00b3, m\u00b3, liters and US gallons. For boxes, the <em>Dimensional (shipping) weight<\/em> in pounds is also shown, and the multi-item mode adds an item-by-item breakdown table.<\/li>\n<\/ol>\n<h2>What a Cubic Foot Represents<\/h2>\n<p>A cubic foot is the volume of a cube that is exactly one foot (12 inches) on each side: \\(1 \\times 1 \\times 1\\) ft. Because it is a three-dimensional unit, one cubic foot contains \\(12^3 = 1{,}728\\) cubic inches, and 27 cubic feet make up one cubic yard. In metric terms, \\(1\\ \\text{ft}^3 \\approx 28.32\\) liters or \\(0.02832\\ \\text{m}^3\\), since one foot is defined as exactly 0.3048 m.<\/p>\n<p>Cubic feet show up everywhere volume matters in everyday life: the capacity of a refrigerator, a shipping box, a planter, a concrete pour, or the airflow rating of an HVAC system (CFM is literally cubic feet per minute). Moving companies and freight carriers quote prices partly by total cubic feet, and soil, mulch and concrete are often sold by the cubic yard \u2014 which is just 27 ft\u00b3.<\/p>\n<p>Because the calculator converts every result to common units at once, you can check a figure against a supplier's quote without doing arithmetic by hand. For example, if you need to fill a raised bed described in liters, you can verify it equals about 14.4 ft\u00b3 and decide whether two cubic-yard bags will cover it.<\/p>\n<p>Note the <em>dimensional weight<\/em> figure for boxes: parcel carriers compute it as \\(L \\times W \\times H\\) in inches divided by 139, and bill whichever is greater \u2014 dimensional or actual weight. A light but bulky box can therefore cost as if it weighed far more.<\/p>\n<h2>Tips, Assumptions and Limitations<\/h2>\n<ul>\n<li>All dimensions are treated as exact, and boxes, rooms and cylinders are assumed to be perfect \u2014 no allowance is made for wall thickness, packaging voids, asymmetries or irregular shapes.<\/li>\n<li>For rooms, include only the space you actually want to measure: exclude built-in furniture for storage estimates, or use floor-to-ceiling height only if you truly plan to fill the whole height. Realistic loading never fills a room or truck completely \u2014 add a 10\u201320 % buffer for packing gaps.<\/li>\n<li>The feet-plus-inches fields convert 12 or more inches automatically (18 in becomes 1 ft 6 in), but for purely inch-based measurements it is simpler to enter each dimension with the <em>in<\/em> unit selected.<\/li>\n<li>The dimensional weight uses the standard divisor 139 in\u00b3\/lb used by most US parcel carriers; express and freight services may use different divisors, so confirm with your carrier before relying on the figure.<\/li>\n<li>Results are rounded for display: 4 decimals for ft\u00b3, 2 decimals for liters and in\u00b3. Plan material purchases with a small margin on top.<\/li>\n<\/ul>\n<h2>Handy Conversion Reference<\/h2>\n<table>\n<thead>\n<tr>\n<th>1 cubic foot equals\u2026<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Cubic inches<\/td>\n<td>1,728 in\u00b3<\/td>\n<\/tr>\n<tr>\n<td>Cubic yards<\/td>\n<td>0.03704 yd\u00b3 (1\/27)<\/td>\n<\/tr>\n<tr>\n<td>Cubic meters<\/td>\n<td>0.02832 m\u00b3<\/td>\n<\/tr>\n<tr>\n<td>Liters<\/td>\n<td>28.3168 L<\/td>\n<\/tr>\n<tr>\n<td>US gallons<\/td>\n<td>7.4805 gal<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>If you also work with metric plans, the <a href=\"https:\/\/wpcalc.com\/en\/converters\/meters-to-feet\/\">meters to feet converter<\/a> pairs well with this tool, and the <a href=\"https:\/\/wpcalc.com\/en\/converters\/feet-and-inches-calculator\/\">feet and inches calculator<\/a> handles mixed-unit arithmetic.
