One litre of water has a mass of almost exactly one kilogram when measured at its maximal density, which occurs at about 4 °C. It follows, therefore, that 1000th of a litre, known as one millilitre (1 mL), of water has a mass of about 1 g; 1000 litres of water has a mass of about 1000 kg (1 tonne or megagram). This relationship holds because ...
The British imperial gallon (frequently called simply "gallon") is defined as exactly 4.54609 dm 3 (4.54609 litres). [4] It is used in some Commonwealth countries, and until 1976 was defined as the volume of water at 62 °F (16.67 °C) [5] [6] whose mass is 10 pounds (4.5359237 kg).
Both the 42-US-gallon (159 L) barrels (based on the old English wine measure), the tierce (159 litres) and the 40-US-gallon (150 L) whiskey barrels were used. Also, 45-US-gallon (170 L) barrels were in common use. The 40 gallon whiskey barrel was the most common size used by early oil producers, since they were readily available at the time.
In 1824, these units were replaced with a single system based on the imperial gallon. [a] Originally defined as the volume of 10 pounds (4.54 kg) of distilled water (under certain conditions), [b] then redefined by the Weights and Measures Act 1985 to be exactly 4.546 09 L (277.4 cu in), the imperial gallon is close in size to the old ale gallon.
6.228835459×10 9 imperial gallons Alternatively, 35.32 tmcft = 1 cubic kilometer (km 3 ) is the standard unit used by Central Water Commission of Government of India for reporting gross and effective storage capacities of dams in India in National Register of Large Dams (NRLD).
1.5 US gallons (5.7 litres) of ethanol has the same energy content as 1.0 US gal (3.8 L) of gasoline. The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above)
For example, the freezing point of water is 0 °C and 32 °F, and a 5 °C change is the same as a 9 °F change. Thus, to convert from units of Fahrenheit to units of Celsius, one subtracts 32 °F (the offset from the point of reference), divides by 9 °F and multiplies by 5 °C (scales by the ratio of units), and adds 0 °C (the offset from the ...
