The tonne (/ t ʌ n / ⓘ or / t ɒ n /; symbol: t) is a unit of mass equal to 1,000 kilograms.It is a non-SI unit accepted for use with SI.It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton (United States customary units) and the long ton (British imperial units).
For the cubic ton, the situation is more complex—there are different cubic tons for different materials. The 1964 Reader's Digest Great Encyclopaedic Dictionary gave the following ton-derived volumes: Timber, 40 cubic feet or 480.0 bd ft or 1.133 m 3; Stone, 16 cubic feet (0.453 m 3) Salt, 42 US bushels (1.480 m 3) Lime, 40 US bushels (1.410 m 3)
The ton is derived from the tun, the term applied to a cask of the largest capacity.This could contain a volume between 175 and 213 imperial gallons (210 and 256 US gal; 800 and 970 L), which could weigh around 2,000 pounds (910 kg) and occupy some 60 cubic feet (1.7 m 3) of space.
Sustainable techniques attempt to slow erosion through the use of cover crops in order to build organic matter in the soil. The United States loses almost 3 tons of topsoil per acre per year. [16] 1 inch (2.5 cm) of topsoil can take between 500 [17] and 1,000 years [18] to form naturally, making the rate of topsoil erosion a serious ecological ...
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

Wheat at 13.5% moisture by weight: 60 lb [7] (27.2155 kg) Soybeans at 13% moisture by weight: 60 lb [ 10 ] (27.2155 kg) Other specific values are defined (and those definitions may vary within different jurisdictions, including from state to state in the United States) for other grains, oilseeds, fruits, vegetables, coal, hair and many other ...
The soil bulk density of cultivated loam is about 1.1 to 1.4 g/cm 3 (for comparison water is 1.0 g/cm 3). [48] Contrary to particle density, soil bulk density is highly variable for a given soil, with a strong causal relationship with soil biological activity and management strategies. [ 49 ]
