The general relationship between absorbed dose and equivalent dose can be represented as. H = Q ⋅ D. where H is the equivalent dose, D is the absorbed dose, and Q is a dimensionless quality factor. Thus, for any quantity of D measured in Gy, the numerical value for H measured in Sv may be different.
Imperial units. ≈ 271,330 imp gal. The acre-foot is a non- SI unit of volume equal to about 1,233 m 3 commonly used in the United States in reference to large-scale water resources, such as reservoirs, aqueducts, canals, sewer flow capacity, irrigation water, [1] and river flows. An acre-foot equals approximately an eight-lane swimming pool ...
The former Weights and Measures office in Seven Sisters, London (590 Seven Sisters Road). The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments.
The US fluid ounce is based on the US gallon, which in turn is based on the wine gallon of 231 cubic inches that was used in the United Kingdom prior to 1824. With the adoption of the international inch, the US fluid ounce became 1⁄128 gal × 231 in 3 /gal × (2.54 cm/in) 3 = 29.5735295625 mL exactly, or about 4% larger than the imperial unit.
1 firkin [9 Imp. gal.]: A Dutch word meaning "little Fourth"; a measure that was a fourth of a barrel. A small cask similar to the anker. 1 kilderkin = 2 firkins [18 Imp. gal.]: A Dutch word meaning "little quintal"; a measure that was a half of a barrel. 1 barrel = 4 firkins = 2 kilderkins [36 Imp. gal.] 1 hogshead = 6 firkins = 3 kilderkins ...
Catalytic converter. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including ...
A standardized hogshead measured 48 inches (1.22 m) long and 30 inches (76.20 cm) in diameter at the head (at least 550 L or 121 imp gal or 145 US gal, depending on the width in the middle). Fully packed with tobacco, it weighed about 1,000 pounds (454 kg) [citation needed] . A hogshead in Britain contains about 300 L (66 imp gal; 79 US gal).
Peak ground acceleration can be expressed in fractions of g (the standard acceleration due to Earth's gravity, equivalent to g-force) as either a decimal or percentage; in m/s 2 (1 g = 9.81 m/s 2); or in multiples of Gal, where 1 Gal is equal to 0.01 m/s 2 (1 g = 981 Gal).
