About these units
Femtoliter (fL)
A femtoliter represents 10⁻¹⁵ liters and is commonly used in hematology, particularly in describing red blood cell size. A typical red blood cell has a volume of roughly 80–100 fL, making this unit ideal for medical diagnostics. Beyond medicine, femtoliters are used in microfluidics and nanoparticle research, where reaction chambers or droplets often hold only a few dozen femtoliters of liquid. The femtoliter exemplifies how modern science pushes measurement into realms dominated by statistical motion, molecular interactions, and quantum effects—scales that once seemed impossible to quantify.
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.
