Converting Cubic Feet to Liters

Converting Cubic Feet to Liters This example problem demonstrates how to convert cubic feet to liters. The cubic foot is the U.S.  and imperial unit of volume for a cube that has sides that are 1 foot in length. The liter is an SI or metric unit of volume. It is the volume of a cube that has sides that are 10 centimeters in length. The conversion between the two systems is fairly common, particularly if youre working with liquefied gases. Cubic Feet to Liter Conversion Problem What is this  volume  of  1 cubic foot  in liters? Many conversion factors are difficult to remember. Converting  cubic feet to liters would fall into this category. The unit-canceling method  is helpful in performing this kind of problem because it uses many easily remembered conversions that relate the original units to the final units, as follows: 1 foot 12 inches1 inch 2.54 centimeters1,000 cubic centimeters 1 liter Using these steps, you can express feet to centimeters as: Distance in cm (distance in ft) x (12 in/1 ft) x (2.54 cm/1 in)Distance in cm (distance in ft) x 30.48 cm/ft Convert these distances into volume measurements of cm3 and ft3: Cube volume (linear measurement)3, so:Volume in cm3 [(distance in feet) x 30.48 cm/ft]3Volume in cm3 (volume in ft3) x 28316.85 cm3/ft3 Convert cubic centimeters to liters: Volume in liters (volume in cm3) x (1 L/1,000 cm3)Volume in liters (volume in cm3)/1,000 L/cm3 Insert the cubic volume from the previous step: Volume in liters [(volume in ft3) x 28316.85 cm3/ft3)]/1,000 L/cm3Volume in liters (volume in ft3) x 28.317 L/ft3 Now you have your conversion factor of cubic feet to liters. Insert 1 cubic foot into the volume in ft3 part of the equation: Volume in liters (1 ft3) x 28.317 L/ft3Volume in liters 28.317 L Therefore, one cubic foot is equal to 28.317 liters of volume. Liter to Cubic Feet Example The conversion factor works the other way, too. For example, convert 0.5 liter to cubic feet. Use the conversion factor 1 cubic foot 28.317 liters: Cubic feet (0.5 liter) x (1 cubic foot / 28.317 liters) The liters cancel out on the top and bottom, leaving you with 0.5 / 28.317, and giving an answer of 0.018 cubic feet. Tips for Success The key to working the unit conversion correctly is to make certain the unwanted unit cancels out and leaves the desired unit. Its also worthwhile to keep track of significant digits. Remember there are about 28 liters in a cubic foot. If youre converting from cubic feet to liters, expect to get a larger number than you started with. If youre converting from cubic feet to liters, your final answer will be a smaller number.
