What does one kilowatt-second represent?

One kilowatt-second represents one kilowatt of power applied for one second, which equals one kilojoule of energy.

What is the thermochemical British thermal unit (Btu th)?

The Btu (th) is the heat needed to raise one pound of water by one degree Fahrenheit, based on the thermochemical calorie and approximately 1,055 joules.

When should I use this kilowatt-second to Btu (th) conversion?

Use this conversion to relate short-duration energy pulses in engineering to traditional heat energy units common in heating, ventilation, and fuel energy content assessments.
