Introduction
Energy and power are important physical quantities used
in physics, engineering, electricity, industries and daily life.
Different fields use different measurement units, therefore
conversion between units is necessary.
What is Energy?
Energy is the ability to perform work.
The SI unit of energy is Joule (J).
Common energy units include kWh, calorie and BTU.
What is Power?
Power is the rate at which energy is transferred or used.
The SI unit of power is Watt (W).
