About Converting Cubic feet to Kiloliters
Cubic foot and Kiloliter appear side by side at fuel pumps and on beverage labels, since the US measures liquids in gallons while most of the world uses liters. Cubic foot is most often used for us natural gas utility billing (often in hundreds or thousands of cubic feet).
Formula
kiloliters = cubic feet × 0.028316846592
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot equals 0.028316846592 base units, and 1 kiloliter equals 1 base unit, so dividing one by the other gives the direct cubic foot-to-kiloliter factor of 0.028316846592.
Simple example
1 ft3 × 0.02831684659 = 0.0283168466 kL
1 cubic foot = 0.0283168466 kiloliters.
Real-world example
10 ft3 × 0.02831684659 = 0.2831684659 kL
10 cubic feet = 0.2831684659 kiloliters.
