The Winchester bushel is the volume of a cylinder 18.5 in (470 mm) in diameter and 8 in (200 mm) high, which gives an irrational number, of approximately 2150.4202 cubic inches. [4] The modern American or US bushel is rounded to exactly 2150.42 cubic inches, a difference of less than one part per ten million.
The dry gallon's implicit value in the US system was originally one-eighth of the Winchester bushel, which was a cylindrical measure of 18.5 inches (469.9 mm) in diameter and 8 inches (203.2 mm) in depth, making it an irrational number of cubic inches; its value to seven significant digits was 268.8025 cubic inches (4.404884 litres), from an ...

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 ...
In the US, the dry quart and dry pint are exactly 15121 / 92400 larger than their liquid counterparts, while the dry barrel is exactly 1 / 33 smaller than the fluid barrel, except for barrels of beer (dry barrels are exactly 5 / 341 smaller) and barrels of oil (dry barrels are exactly 3 / 11 smaller).
In Scotland, the peck was used as a dry measure until the introduction of imperial units as a result of the Weights and Measures Act 1824.The peck was equal to about 9 litres (1.98 Imp gal) (in the case of certain crops, such as wheat, peas, beans and meal) and about 13 litres (2.86 Imp gal) (in the case of barley, oats and malt).
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 ]
In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg).
