What are Millijoule and Watt-hour

A millijoule (mJ) is a unit of energy equal to one thousandth of a joule. It represents a small amount of energy typically used to measure the energy in scientific contexts. The joule, named after the physicist James Prescott Joule, is the standard unit of energy in the International System of Units (SI). Millijoules are commonly used in applications such as the energy of laser pulses, the heat produced by electrical components, or the kinetic energy of small objects.

A watt-hour (Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time. It represents a specific amount of electrical energy and is commonly used by electricity providers for billing purposes. The watt-hour is a standard unit of energy that encompasses the total amount of work done or energy provided over time. It's particularly useful in the context of electrical systems for measuring electricity consumption by appliances and for calculating electrical costs over time.

History of Millijoule and Watt-hour

The Millijoule to Watt-hour Converter has its origins in the need to translate small units of energy, commonly used in physics and engineering, into more tangible terms like watt-hours, which are easier to comprehend in the context of everyday electrical usage.
