What does attojoule/second measure?

Attojoule/second measures extremely small rates of energy transfer or dissipation, equal to 10^-18 watts.

Why convert from aJ/s to kJ/h?

Converting from aJ/s to kJ/h translates tiny per-second energy rates into a more interpretable per-hour scale for easier comparison.

In which fields is this conversion most useful?

It is useful in quantum device engineering, nanoscale thermal metrology, building physics, metabolic studies, and laboratory calorimetry.

What Is This Tool?

This tool helps you convert power measurements from attojoule per second (aJ/s), a very small unit of energy transfer per second, to kilojoule per hour (kJ/h), a unit representing energy transfer over an hourly period. It simplifies interpreting tiny power values in a more practical time scale.

How to Use This Tool?

Enter the power value in attojoule/second you want to convert
Select the from-unit as attojoule/second [aJ/s]
Select the to-unit as kilojoule/hour [kJ/h]
Click convert to get the equivalent value in kilojoule/hour

Key Features
