1 m³ = 0.000811 ac⋅ft. 5 m³ = 0.004054 ac⋅ft. 10 m³ = 0.008107 ac⋅ft. 25 m³ = 0.020268 ac⋅ft. 50 m³ = 0.040536 ac⋅ft. 100 m³ = 0.081071 ac⋅ft.
What is Cubic Meters?
Cubic Meters (m³) is a unit of volume. A cubic meter is the SI base unit of volume defined as the volume of a cube with edges one meter in length. It exactly equals 1,000 liters or 1,000,000 cubic centimeters. This unit is the standard for volume measurement in science, industry, and commerce worldwide according to the International System of Units [bipm-si-brochure]. The cubic meter was established with the adoption of the meter as a fundamental unit by the French Academy of Sciences in the late 18th century. It became a formal SI unit with the 1960 SI system definition and is maintained by the Bureau International des Poids et Mesures (BIPM) [bipm-si-brochure]. Cubic meters are used globally in fields such as construction, shipping, and water management. Countries using the metric system rely on this unit for large volume measurements, including natural gas volumes and building materials [bipm-si-brochure].
What is Acre-Feet?
Acre-Feet (ac⋅ft) is a unit of volume. An acre-foot is the volume of water covering one acre to a depth of one foot, equal to 1,233,481.8 liters or approximately 1.234 million cubic meters. It is calculated by multiplying the area (1 acre = 4,046.86 square meters) by the depth (1 foot = 0.3048 meters). This unit is standard in water resource management for measuring reservoir capacity and irrigation volumes. The acre-foot emerged in 19th-century North America during expansion of irrigation systems, particularly in the western United States. Engineers needed a practical unit that combined agricultural land measurement (acres) with water depth to calculate irrigation requirements. By the early 1900s, it became the standard in U.S. water management, especially following the passage of the Newlands Reclamation Act in 1902. Used primarily in the United States for water resource management, reservoir capacity planning, and irrigation accounting. The Bureau of Reclamation and U.S. Geological Survey rely on acre-feet to track water allocation. Canada employs it in some provinces for cross-border water reporting, and Australia uses it informally in agricultural contexts.
Common Misspellings
People often search for this conversion using these alternate spellings: cubic meter, cubic meteres, cubic metrs, kubik meter, cube meters, acre foot, acre-ft, acrefoot. All of these refer to the Cubic Meters to Acre-Feet conversion.
