Convert exawatt to milliwatt
Please provide values below to convert exawatt [EW] to milliwatt [mW], or Convert milliwatt to exawatt.
1 EW = 1.0000e+21 mW. To convert exawatt to milliwatt, multiply the value by 1.0000e+21; to go the other way, divide by it (1 mW = 1.0000e-21 EW). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 EW = 1.0000e+21 mW
- 1 mW = 1.0000e-21 EW
- 10 EW = 1.0000e+22 mW
- 100 EW = 1.0000e+23 mW
How to Convert Exawatt to Milliwatt
1 EW = 1e+21 mW
Example: convert 15 EW to mW:
15 EW = 15 × 1e+21 mW = 1.5e+22 mW

Exawatt
An exawatt (EW) is a unit of power equal to 10^18 watts.
History/Origin
The exawatt is part of the SI prefix system, introduced to represent extremely large power quantities, especially in theoretical physics and astrophysics, as the need to express vast energy outputs grew.
Current Use
Exawatts are primarily used in scientific contexts to describe the power output of large-scale phenomena such as stars and cosmic events; they are rarely used in everyday measurements.
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.
