A 6.0-liter engine displacement converts to 366 cubic inches. For automotive purposes, cylinder volume unit conversions are rounded. 366.1439 would be a more accurate conversion.
To convert litres to cubic inches, start by multiplying the number of litres by 1,000 to convert to cubic centimetres. Since 1 cubic inch is equal to 16,387 cubic centimetres, divide the answer by 16,387 to get the final answer.
To find out what an engine measured in cubic inches measures in litres, reverse the process. A 350-cubic-inch engine converts to 5.7 litres by multiplying 350 by 16.387, then dividing by 1,000 and rounding to the nearest tenth.
