ncal(nanocalorie)

A nanocalorie (ncal) is a unit of energy in the field of energy measurements. It is a submultiple of the calorie, which is a unit commonly used to quantify energy, particularly in the context of food, nutrition, and heat transfer. The prefix "nano" denotes that it is one-billionth (10⁻⁹) of a calorie. Therefore, one nanocalorie is equivalent to 0.000000001 (10⁻⁹) calories. In the International System of Units (SI), the energy is usually measured in joules; thus, 1 nanocalorie is approximately equal to 4.184 picojoules (pJ). Nanocalories are generally used when dealing with very small amounts of energies, such as in microscopic or nano-level energy exchanges.

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.
