Convert milliwatt to megajoule/second
Please provide values below to convert milliwatt [mW] to megajoule/second [MJ/s], or Convert megajoule/second to milliwatt.
1 mW = 1e-09 MJ/s. To convert milliwatt to megajoule/second, multiply the value by 1e-09; to go the other way, divide by it (1 MJ/s = 1000000000 mW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 mW = 1e-09 MJ/s
- 1 MJ/s = 1000000000 mW
- 10 mW = 1e-08 MJ/s
- 100 mW = 1e-07 MJ/s
How to Convert Milliwatt to Megajoule/second
1 mW = 1e-09 MJ/s
Example: convert 15 mW to MJ/s:
15 mW = 15 × 1e-09 MJ/s = 1.5e-08 MJ/s

Milliwatt
A milliwatt (mW) is a unit of power equal to one thousandth of a watt, used to measure small amounts of power.
History/Origin
The milliwatt was introduced as part of the metric system to provide a convenient unit for measuring low power levels, especially in electronics and telecommunications, with its usage expanding alongside the adoption of the watt as the standard power unit.
Current Use
Milliwatts are commonly used today in electronics, audio equipment, and wireless communication devices to specify power levels, such as in battery-powered devices, LED brightness, and signal transmission power.
Megajoule/second
A megajoule per second (MJ/s) is a unit of power equivalent to one megajoule of energy transferred or converted per second, where 1 megajoule equals 1,000,000 joules.
History/Origin
The megajoule per second has been used in scientific and engineering contexts to quantify large-scale power, especially in fields like physics and energy systems, as a convenient unit for expressing high power levels. It is derived from the SI units of energy (joule) and time (second).
Current Use
Today, MJ/s is primarily used in scientific research, energy production, and engineering to describe high power outputs, such as in power plants, large-scale energy systems, and theoretical calculations involving energy transfer rates.
Frequently Asked Questions
What is 1 milliwatt in megajoule/second?
1 milliwatt (mW) = 1e-09 megajoule/second (MJ/s).
How do you convert milliwatt to megajoule/second?
Multiply the milliwatt value by 1e-09. For example, 25 mW × 1e-09 = 2.5e-08 MJ/s.
What is 10 milliwatt in megajoule/second?
10 mW = 1e-08 MJ/s.
Which unit is larger, the milliwatt or the megajoule/second?
The megajoule/second is the larger unit: 1 mW equals only 1e-09 MJ/s.
