What does Btu (th)/second measure?

Btu (th)/second measures the rate of heat transfer, specifically one thermochemical British thermal unit delivered each second.

When should I use kilojoule/hour as a unit of power?

Kilojoule/hour is used to describe smaller to moderate energy rates over hourly periods, such as in building physics or metabolic energy expenditure.

Why might my conversion results vary slightly?

Differences in Btu standards and assumptions of steady-state conditions can cause variations in conversion accuracy.
