About these units
Cubic Millimeter (mm³)
A cubic millimeter is the volume of a cube exactly 1 millimeter on each side, equal to 10⁻⁹ cubic meters or 0.001 milliliters. It is a very small volume, frequently used in medical imaging, microfluidics, materials science, and cell biology. In anatomy and radiology, tissue or tumor volumes are often quantified in cubic millimeters to express small but clinically significant structures. In engineering, mm³ can describe the displacement of precision components or the volume of micro-machined cavities. Microfluidic research—where entire laboratories are miniaturized onto chips—depends heavily on mm³ and smaller units, as channels and chambers hold extremely tiny volumes. Its precision scale makes it invaluable for applications requiring meticulous material control.
Acre-Foot (ac*ft)
An acre-foot represents the volume of water needed to cover one acre of land to a depth of one foot—approximately 1,233.48 cubic meters or 325,851 gallons. This unit is foundational in water resource management throughout the western United States, where large-scale irrigation, reservoir planning, and drought analysis depend on acre-foot measurements. For example, major reservoirs like Lake Mead and Lake Powell hold billions of acre-feet. In agriculture, irrigation districts track water rights and allocations using acre-feet, making it a key component of water law. Its scale is ideal for representing the enormous water needs associated with farming, urban expansion, and environmental preservation.
