The 5W crawler heating pad can use 0.12 kWh of electricity a day. We generally use degrees to measure the amount of electricity consumed by a certain electrical appliance. Then the meaning of degree is the power consumed by an appliance with a power of 1000 watts that works continuously for an hour. So the algorithm of electrical power consumption is to compare its power with 1000 watts, and then multiply it by the use time. According to the data of this question, 0.005×24=0.12.
