Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Attowatt and kWh measure different quantities, so no single result applies.

Formula
Attowatt (aW) measures power, while kWh (kWh) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
aW relates to its own power base unit by a factor of 0. kWh relates to its own energy base unit by a factor of 3600000.

Frequently asked questions
Can Attowatt be converted to kWh?
Not directly. Attowatt measures power and kWh measures energy. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Attowatt used for?
The Attowatt (aW) is a unit of power. Attowatt is 1e-18 watt units.
What is kWh used for?
The kWh (kWh) is a unit of energy. A kilowatt-hour is 3.6 million joules.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since Attowatt and kWh don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Attowatt to instead?
Use another power unit, such as one of the related Attowatt conversions linked below.
What should I convert kWh to instead?
Use another energy unit, such as one of the related kWh conversions linked below.

About this conversion
This page compares Attowatt (aW) and kWh (kWh) within the engineering converter.
Attowatt is 1e-18 watt units. A kilowatt-hour is 3.6 million joules.
Because Attowatt measures power and kWh measures energy, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
