What is the formula for calculating the cost of electricity?

To calculate the cost of electricity, you need to know T1- meter reading and T2- previous reading. Find their difference ΔT = T2-T1.
The cost can be easily calculated using the formula:
P = C * ΔT, where P is the desired cost, C is the price of electricity per 1 kW * hour, set by the energy company.
