About Cubic Inches
A cubic inch (in³) is the volume of a cube with sides of one inch (25.4 mm), equal to approximately 16.387 mL. It is widely used in US engineering and manufacturing - engine displacement was traditionally described in cubic inches (a 350 in³ V8 engine displaces 5.7 liters), and product specifications for items sold in the US frequently reference cubic inches. Speaker cabinet volumes, wine bottle capacities in older US standards, refrigerator compartment sizes, and box shipping calculations in imperial units all use cubic inches. One liter equals approximately 61.024 cubic inches.
About Pecks
A peck (pk) is a dry volume unit in the US customary system equal to 2 dry gallons or 8 dry quarts - approximately 8.810 liters. It was historically used to measure grain, produce, and bulk goods at market - a 'peck of potatoes' or 'peck of apples' was a standard quantity. The nursery rhyme 'Peter Piper picked a peck of pickled peppers' has made the peck culturally familiar even though it is rarely used in modern commerce. Four pecks equal one US bushel. In agriculture, pecks still appear in older US crop yield tables, traditional market records, and historical American cookbooks.
