The factor is exact rather than rounded: imperial and US units have been defined from the metric ones since 1959, so the conversion introduces no error of its own. What you see below is arithmetic, not an approximation.
The cubic meter is the volume of a cube one meter on each side, 1,000 liters. Water bills, natural gas, concrete and shipping are measured in it; a standard 20-foot container holds about 33 m³.
The US gallon is exactly 231 cubic inches, about 3.785 liters, and prices gas and milk in the United States. The imperial gallon used in the United Kingdom is larger, about 4.546 liters, so a gallon is not the same on both sides of the Atlantic.
