Million standard cubic feet per day is a unit of measurement for gases that is predominantly used in the United States.It is frequently abbreviated MMSCFD. MMSCFD is commonly used as a measure of natural gas, liquefied petroleum gas, compressed natural gas and other gases that are extracted, processed or transported in large quantities.
ERIS—Energy Resource Interconnection Service (electricity) ERO—Electric Reliability Organization. The US designated NERC as its ERO. ERoEI—Energy returned on energy invested; ERRA—Energy Regulators Regional Association; ESCO—Energy service company; ESI—Environmental Sustainability Index; ESMAP—Energy Sector Management Assistance ...
A unit of electrical energy, particularly for utility bills, is the kilowatt-hour (kWh); [3] one kilowatt-hour is equivalent to 3.6 megajoules. Electricity usage is often given in units of kilowatt-hours per year or other periods. [4] This is a measurement of average power consumption, meaning the average rate at which energy is transferred ...
ton of refrigeration (imperial) ≡ 2240 lb × ice IT / 24 h: ice IT = 144 °F × 2326 J/kg⋅°F ≈ 3.938 875 × 10 3 W: ton of refrigeration (IT) ≡ 2000 lb × ice IT / 24 h: ice IT = 144 °F × 2326 J/kg⋅°F ≈ 3.516 853 × 10 3 W: watt (SI unit) W The power which in one second of time gives rise to one joule of energy.

The pressure definition differs between sources, but are all close to normal sea level air pressure. A pressure of 14.696 pounds per square inch (1.00000 atm; 101.325 kPa). [2] This is the same pressure as the SI system standard pressure. Gives 1.1953 moles per scf. A pressure of 101.35 kilopascals (1.0002 atm; 14.700 psi). [2]
Just as horsepower and candlepower were intuitive units of measure for people living through the transition from horse to steam power [3] and from flame-based to electric lighting, so was the ton of refrigeration an intuitive unit of measure during a technological change, as the ice trade gradually included growing percentages of artificial ice ...
Full Load hour is a measure of the degree of utilisation of a technical system. [1] [2] [3] Full load hours refer to the time for which a plant would have to be operated at nominal power in order to convert the same amount of electrical work as the plant has actually converted within a defined period of time, during which breaks in operation or partial load operation can also occur.
List of orders of magnitude for energy; Factor (joules) SI prefix Value Item 10 −34: 6.626 × 10 −34 J: Energy of a photon with a frequency of 1 hertz. [1]8 × 10 −34 J: Average kinetic energy of translational motion of a molecule at the lowest temperature reached (38 picokelvin [2] as of 2021)
