Convert watt to exawatt
Please provide values below to convert watt [W] to exawatt [EW], or Convert exawatt to watt.
1 W = 1.0000e-18 EW. To convert watt to exawatt, multiply the value by 1.0000e-18; to go the other way, divide by it (1 EW = 1.0000e+18 W). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 W = 1.0000e-18 EW
- 1 EW = 1.0000e+18 W
- 10 W = 1.0000e-17 EW
- 100 W = 1.0000e-16 EW
How to Convert Watt to Exawatt
1 W = 1e-18 EW
Example: convert 15 W to EW:
15 W = 15 × 1e-18 EW = 1.5e-17 EW

Watt
The watt (W) is the SI unit of power, defined as one joule per second, representing the rate of energy transfer or conversion.
History/Origin
The watt was named after James Watt, the Scottish engineer and inventor, in 1889. It was adopted as the SI unit of power to standardize measurements in science and engineering.
Current Use
The watt is widely used today to quantify power in electrical devices, engines, and energy consumption, serving as a fundamental unit in physics, engineering, and everyday applications.
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.
Frequently Asked Questions
What is 1 watt in exawatt?
1 watt (W) = 1.0000e-18 exawatt (EW).
How do you convert watt to exawatt?
Multiply the watt value by 1.0000e-18. For example, 25 W × 1.0000e-18 = 2.5000e-17 EW.
What is 10 watt in exawatt?
10 W = 1.0000e-17 EW.
Which unit is larger, the watt or the exawatt?
The exawatt is the larger unit: 1 W equals only 1.0000e-18 EW.
