About these units
Cubic Decimeter (dm³)
A cubic decimeter is defined as 1 liter, since it is the volume of a cube 10 centimeters per side. Though equivalent to the liter, dm³ is often used in engineering and physics because it fits neatly into the SI geometric framework. This unit is convenient when working with densities (kg/dm³), where the equivalence of 1 dm³ and 1 L simplifies many calculations involving fluids and materials. While the liter dominates everyday usage, the cubic decimeter is favored in technical contexts where a strong geometric interpretation is needed—for example, in tank sizing, volumetric flow calculations, or experiments involving water displacement.
Acre-Inch (ac*in)
An acre-inch equals 1/12 of an acre-foot, representing the water required to cover one acre to a depth of one inch. Irrigation planners and farmers often use acre-inches to fine-tune watering schedules for crops. Because plants require precise hydration, the acre-inch allows for granular control of irrigation needed for soil management and crop health. Agronomists also use acre-inches to convert rainfall into usable water volume estimates for agricultural regions, linking meteorology with farm management.
