dW h(deciwatt hour)

In the field of energy, unit dWh (deciwatt hour) refers to a measure of energy consumption, production or storage. It represents the amount of energy consumed, produced or stored when one-tenth of a watt (0.1 watt) of power is used continuously for one hour. The deciwatt hour is a smaller unit than the more commonly used watt-hour (Wh).

1 dWh is equal to 0.1 Wh, or 100 milliwatt-hours (mWh). This unit is useful for measuring small amounts of energy consumption, such as in low-power devices or in situations where energy consumption must be closely monitored for efficiency.

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.
