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.

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.
