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).
The price elasticity of drinking water demand by urban households is typically low. In European countries it ranges between -0.1 and -0.25, i.e. the demand for water decreases by 0.1% to 0.25% for every 1% increase in tariffs. In Australia and the United States price elasticity is somewhat higher in the range of -0.1 and -0.4. [15]
Municipal volumetric water measurements, including city water flow and cost per unit on a residential water bill, can either be measured in gallons, cubic feet, or cubic meters, with gallons being the most commonly used. Water bottles for personal use can have their capacity measured in fluid ounces or liters. For ounces, the measurements are ...
Many folks opt to aim for the nice, square number of 1 gallon of water a day (for reference, 2.7 liters equal about 0.7 gallons), so we looked into the health benefits of drinking that much H20 ...
This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/cu ft (9.3 kWh/m 3) of natural gas and 114,000 BTU/US gal (8.8 kWh/L) for gasoline). [22] One GGE of CNG pressurized at 2,400 psi (17 MPa) is 0.77 cubic feet (22 litres; 5.8 US gallons).
In the United States most utilities bill only to the nearest 100 or 1,000 gallons (10 to 100 ft 3, 1 to 10 m 3), and often only read the leftmost 4 or 5 numbers on the display wheels. Using the above example, they would read and bill 1,234, rounding to 1,234,000 gallons based on a 1,000-gallon billing resolution.
Within this choice set, the preferred water tariff depends on multiple factors including: the goals of water pricing; the capacity of a water services supplier to allocate its costs, to price water, and to collect revenues from its customers; the price responsiveness of water consumers; and what is considered to be a fair or just water tariff.

As of 2012, a household consuming 20 m 3 per month and that has three "chargeable fittings" faces a water bill of S$32.5 per month and a sewer bill of S$15 per month, both including all taxes. The total of S$47.5 (USD 37.7) per month corresponds to S$2.38/m 3 (US$1.88/m 3). Industrial water tariffs are set lower at S$0.52/m 3. [74]
