What is kilojoule per hour (kJ/h)?

Kilojoule per hour measures power as 1,000 joules transferred or consumed every hour, used to describe small-to-moderate energy rates over long durations.

Why convert kJ/h to joule per second (J/s)?

Converting to J/s expresses energy transfer in standard SI power units, enabling comparison and calculation of instantaneous power rates.

Can this conversion handle fluctuating power rates accurately?

No, this conversion is most accurate for steady or average power rates, as it may not capture transient changes in energy transfer.

Examples

Convert 5 kJ/h to J/s: 5 × 0.2777777778 = 1.388888889 J/s
Convert 10 kJ/h to J/s: 10 × 0.2777777778 = 2.777777778 J/s

Common Use Cases

Expressing heat loss or gain rates in building physics over hourly periods.
Reporting energy expenditure rates in metabolic or exercise studies.
Analyzing low-rate heat transfer in laboratory calorimetry.
Measuring electrical power consumption and mechanical power output in devices and engines.
Design and analysis of thermodynamics and HVAC systems.

Tips & Best Practices

Ensure energy rates are consistently referenced over the same time basis before converting.
Use this converter for steady or average power values since instantaneous fluctuations may not be captured.
Cross-check units when dealing with energy transfer rates across hourly and per-second scales.
Apply the conversion rate accurately to maintain consistency in power analysis.

Limitations

The conversion assumes steady energy transfer rates and may not account for transient fluctuations.
Instantaneous power can vary, so direct conversions from hourly to per-second units might overlook short-term changes.
Accuracy depends on the precision of input values and consistent time referencing.
