Frequently asked questions
What is the source unit in this conversion?
The source unit is the Watt (W). The watt is one joule per second.
What is the destination unit in this conversion?
The destination unit is the Nanowatt (nW). Nanowatt is 1e-9 watt units.
How do I convert Watt to Nanowatt?
Multiply the Watt value by 1e+09. For example, 10 W × 1e+09 = 1e+10 nW.
Is the Watt to Nanowatt conversion exact?
Yes. Both units belong to the same engineering measurement family (power), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Watt needs to be compared with, or reported in, Nanowatt, such as in engineering, scientific, or industrial calculations.
Can I convert Nanowatt back to Watt?
Yes. Multiply the Nanowatt value by 1e-09 to get Watt.

About this conversion
This page converts Watt (W) to Nanowatt (nW) within the engineering converter.
The watt is one joule per second. Nanowatt is 1e-9 watt units.
The formula is nW = W × 1e+09, based on each unit's fixed relationship to the power base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
