Convert milliwatt to exajoule/second
Please provide values below to convert milliwatt [mW] to exajoule/second [EJ/s], or Convert exajoule/second to milliwatt.
1 mW = 1.0000e-21 EJ/s. To convert milliwatt to exajoule/second, multiply the value by 1.0000e-21; to go the other way, divide by it (1 EJ/s = 1.0000e+21 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 = 1.0000e-21 EJ/s
- 1 EJ/s = 1.0000e+21 mW
- 10 mW = 1.0000e-20 EJ/s
- 100 mW = 1.0000e-19 EJ/s
How to Convert Milliwatt to Exajoule/second
1 mW = 1e-21 EJ/s
Example: convert 15 mW to EJ/s:
15 mW = 15 × 1e-21 EJ/s = 1.5e-20 EJ/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.
Exajoule/second
An exajoule per second (EJ/s) is a unit of power representing the transfer or conversion of one exajoule of energy every second.
History/Origin
The exajoule (EJ) is a metric unit of energy introduced as part of the International System of Units (SI) to measure large quantities of energy. The concept of power units like EJ/s emerged with the development of large-scale energy measurement, particularly in fields such as astrophysics and energy production, to quantify extremely high power levels.
Current Use
EJ/s is used primarily in theoretical and large-scale energy discussions, such as in astrophysics, planetary science, and global energy consumption analysis, where extremely high power levels are involved.
Frequently Asked Questions
What is 1 milliwatt in exajoule/second?
1 milliwatt (mW) = 1.0000e-21 exajoule/second (EJ/s).
How do you convert milliwatt to exajoule/second?
Multiply the milliwatt value by 1.0000e-21. For example, 25 mW × 1.0000e-21 = 2.5000e-20 EJ/s.
What is 10 milliwatt in exajoule/second?
10 mW = 1.0000e-20 EJ/s.
Which unit is larger, the milliwatt or the exajoule/second?
The exajoule/second is the larger unit: 1 mW equals only 1.0000e-21 EJ/s.
