Discover the ease of converting energy units from millijoules (mJ) to kilowatt-hours (kWh) with Newtum's precise Millijoule to Kilowatt-hour Converter.

What are Millijoule and Kilowatt-hour

Definition of Millijoule

A millijoule (mJ) is a unit of energy equal to one thousandth of a joule. It's a metric unit commonly used in physics and engineering to measure small amounts of energy. The joule is the standard unit of energy in the International System of Units (SI), and thus the millijoule is a derived unit that provides a convenient scale for measuring energy events that are too small to be expressed in joules.

Definition of Kilowatt-hour

A kilowatt-hour (kWh) is a unit of energy that represents the amount of work done or energy consumed at a rate of one thousand watts over the duration of one hour. It is commonly used as a billing unit for energy delivered to consumers by electric utilities. This measurement provides a standardized way to understand energy usage over time, making it essential for monitoring electrical consumption in homes and businesses alike.

Conversion of Millijoule to Kilowatt-hour

1 mJ = 2.77778e-10 kWh
1 kWh = 3.6e+9 mJ

Example 1:
convert 500 mJ to kWh:
500 mJ = 500 × 2.77778e-10 kWh = 1.38889e-7 kWh

Example 2:
convert 5,000,000 mJ to kWh:
5,000,000 mJ = 5,000,000 × 2.77778e-10 kWh = 0.00138889 kWh

History of Millijoule and Kilowatt-hour

A brief history of the Millijoule to Kilowatt-hour Converter reflects the incremental progress in energy measurement. Millijoules became a standard for small energy measurements with technological advancements. Later, the kilowatt-hour, pivotal in the electrical industry, necessitated a tool for conversion, leading to the creation of such converters that bridge these two units.
