"Degree" is the abbreviation of electric energy measurement unit in daily life, kWh is the usual "degree", which is the unit of electric power, symbol: kW h, and the calculation formula is power multiplied by time.
For power generation, it is the electric energy generated by the operation of the generator with rated power of 1kW 1 hour; For power users, it is the electric energy consumed by electrical appliances with rated power of 1kW 1 hour.
Assume that the power of the electrical equipment is 2500 watts, that is, its power consumption is 2.5 kWh per hour, that is, 2.5 kWh per hour.
The power of the desktop computer is about 160-250W, the power consumption for one hour is 0. 16-0.25 degrees, and the power consumption for six hours is 0.96-10.5 degrees.
The power of a notebook is generally around 60W~80W, with power consumption of 0.06-0.08 kWh for one hour and 0.36-0.48 kWh for six hours.

Common power and power consumption of various household appliances
1, small household appliances
Electric kettle: rated power 1800W, power consumption 1.8 kWh, maximum boiling time of 4-6 minutes, and estimated power consumption of 0. 18 kWh.
Rice cooker: rated power is 800~ 1200W (adjustable), and power consumption is 0.8~ 1.2 kwh per hour.
Microwave oven: rated power (input power)1100 ~1300 w (adjustable), and hourly power consumption 1. 1~ 1.3 degrees.
Electric fan: rated power is 20~70W, and power consumption is 0.02 ~ 0.07kWh per hour. The power of the electric fan is only determined by the size of the electric fan, and the gear (speed) will not affect the power, current and power consumption of the electric fan.
Vacuum cleaner: rated power is 350~ 1200W, and power consumption is 0.35~ 1.2 kWh. The cleaning ability of vacuum cleaner is not completely related to the rated power, but to the working efficiency (the ratio of input power to output power).
Mobile phone charger: the rated power (input power) is 44W (output power 5V 1A) or10w (output power 5V2A), the working current is 0.2A or 0.5A, and the power consumption per hour is 0.044 degrees or 0. 1 1 degree.
