Unit Description
Milliwatt (mW)
Definition
A milliwatt (mW) is a unit of power equal to one thousandth of a watt (0.001 W). It represents very small amounts of power typically found in electronic devices, sensors, and low-power applications.
History
The milliwatt became important with the development of electronics and semiconductor technology. It provided an appropriate scale for describing the power consumption of transistors, integrated circuits, and electronic devices where power efficiency was crucial.
Current Use
Milliwatts are used in electronics for component power ratings, laser output specifications, radio frequency applications, and low-power device design. They're standard for electronic component specifications, sensor power consumption, and precision instruments.
Kilojoule per Hour (kJ/h)
Definition
Kilojoule per hour (kJ/h) is a unit of power representing the rate of energy transfer of one kilojoule per hour. It provides a convenient scale for moderate power measurements in energy system analysis and thermal applications.
History
Kilojoule per hour developed as a practical unit for energy system analysis and thermal calculations. It provided an appropriate scale for describing power in terms of energy per time, particularly useful in heating and cooling system analysis.
Current Use
Kilojoule per hour is used in energy system analysis, thermal calculations, and heating/cooling applications. It's found in energy efficiency calculations, thermal system design, and applications where energy rates are more intuitive than electrical power units.

Conversion Examples
Convert 1 Milliwatt to Kilojoule per Hour
- Conversion Factor: 1 mW = 0.0036 kJ/h
- Conversion Formula: kJ/h = mW ÷ 277.778
- Calculation: 1 mW ÷ 277.778 = 0.0036 kJ/h
Convert 10 Milliwatt to Kilojoule per Hour
- Conversion Factor: 1 mW = 0.0036 kJ/h
- Conversion Formula: kJ/h = mW ÷ 277.778
- Calculation: 10 mW ÷ 277.778 = 0.036 kJ/h
Convert 100 Milliwatt to Kilojoule per Hour
- Conversion Factor: 1 mW = 0.0036 kJ/h
- Conversion Formula: kJ/h = mW ÷ 277.778
- Calculation: 100 mW ÷ 277.778 = 0.36 kJ/h
Convert 1,000 Milliwatt to Kilojoule per Hour
- Conversion Factor: 1 mW = 0.0036 kJ/h
- Conversion Formula: kJ/h = mW ÷ 277.778
- Calculation: 1,000 mW ÷ 277.778 = 3.6 kJ/h
