Dth [EC](decatherm)

A decatherm (Dth) is a unit of energy used primarily in the natural gas and energy industry. It is a non-SI unit, equivalent to 10 therms or 1,000,000 British thermal units (BTU). In simpler terms, a decatherm is a measure of heat energy, with one decatherm representing the amount of molecular_energy">energy required to raise the temperature of 10,000 pounds of water by 1 degree Fahrenheit (1,054.804 × 10^6 Joules).

In the context of energy consumption, pricing, and trading, the term decatherm (Dth) is often used to describe the volume of natural gas required by industries, businesses, and homes. Natural gas providers typically use decatherm as a standard unit to price and measure the amount of gas supplied to customers. Additionally, large-scale energy consumers and gas utilities use decatherm in contracts to determine the volumes of gas delivered, purchased or traded.

MMBTU [IT](million British thermal units)

MMBTU, or Million British Thermal Units (MM is the Roman numeral for one thousand times one thousand), is a unit of measurement in the field of energy. The British thermal unit (BTU) is a unit of heat used in the Imperial and United States customary systems, where one BTU is roughly equivalent to the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

In the context of energy, the MMBTU is often used to measure the energy content of fuels, such as natural gas, oil, or coal. It represents a quantity of one million BTUs and can be used to compare the energy content of different fuels, or to quantify the amount of heat energy produced by a power plant or industrial process.

The MMBTU is an "IT" or "International Table" BTU unit, which means it's based on the IT calorie and is widely used in the global energy sector. It is important to note that the MMBTU can be converted to other energy units, such as kilowatt-hours, joules, or calories, depending on the intended application or standard used in a specific industry or region.
