Use conversion factors to show how many joules of energy you get when you buy 1 kilowatt-hour of electricity.
3 Ιουλ 2024 · Conversion of Power Units. Here’s a conversion table for various units of power, formatted to provide clear conversion factors between watts, kilowatts, megawatts, gigawatts, and horsepower:
Use conversion factors to express the value of a given quantity in different units. It is often necessary to convert from one unit to another. For example, if you are reading a European cookbook, some quantities may be expressed in units of liters and you need to convert them to cups.
Teacher Support. In this section, students learn how work determines changes in kinetic energy and that power is the rate at which work is done. [BL][OL] Review understanding of mass, velocity, and acceleration due to gravity. Define the general definitions of the words potential and kinetic.
The tables below list conversion factors for units of energy and power used in the KEEP Energy Education Activity Guide.
