About these units
Teaspoon (Metric) (tsp (m))
The metric teaspoon is universally fixed at 5 mL, offering complete consistency across countries that use metric culinary measurements. This simplicity is a major advantage over historical teaspoon variations. In metric recipe writing—especially in Australia, New Zealand, and parts of Europe—teaspoons serve as standardized micro-measures that are easy to convert and scale. Its widespread adoption demonstrates the advantages of aligning traditional kitchen practices with the predictable structure of the metric system.
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.
