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 ...
c. 74) declared that, for measures of liquids and unheaped dry volume, a 'quarter' equals eight bushels (64 imperial gallons (290.95 L), where a gallon is defined as a volume of water weight ten troy pounds). [12] The term pail is also used for this unit of dry volume. [13] The 1824 Act delegitimised all previous definitions.

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).
A discharge is a measure of the quantity of any fluid flow over unit time. The quantity may be either volume or mass. Thus the water discharge of a tap (faucet) can be measured with a measuring jug and a stopwatch. Here the discharge might be 1 litre per 15 seconds, equivalent to 67 ml/second or 4 litres/minute. This is an average measure.
The last nine years in the Arctic have all had the highest average temperatures recorded since 1900. That dynamic is the result of a phenomenon called Arctic amplification.
The lake retention time for a body of water with the volume 2,000 m 3 (71,000 cu ft) and the exit flow of 100 m 3 /h (3,500 cu ft/h) is 20 hours.. Lake retention time (also called the residence time of lake water, or the water age or flushing time) is a calculated quantity expressing the mean time that water (or some dissolved substance) spends in a particular lake.
