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).
The ratings are based on EPA's formula, in which 33.7 kWh (121 MJ) of electricity is equivalent to one (U.S.) gallon of gasoline, [8] and the energy consumption of each vehicle during EPA's five standard drive cycle tests simulating varying driving conditions.
The pound or pound-mass is a unit of mass used in both the British imperial and United States customary systems of measurement.Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly 0.453 592 37 kilograms, and which is divided into 16 avoirdupois ounces.

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 ...
A well with 5,000 feet of seawater and 15,000 feet of rock could have an overburden pressures at the bottom as high as 17,220 psi (5000 * 0.444 + 15000 * 1.0). That pressure is reduced at the surface by the weight of oil and gas the riser pipe, but this is only a small percentage of the total.
The national average price for a gallon of gasoline is at $3.50, according to AAA as of Jan. 26, 2023. ... Price of a gallon of gas: $0.33. In 2022 dollars: $2.85. Chris Keating / Wikimedia Commons.
For a 10-gallon fill-up, the added cost is $1.90. For somebody driving 12,000 miles a year who averages 25 miles per gallon, the added cost would be about $91 per year.
The gasoline national average had been in a downward trend from its September 2023 peak of $3.88 per gallon. About a month ago, the average pump price hovered near a one-year low of $3.07.
