What does Btu (th)/second measure?

It measures the rate of heat transfer equal to one thermochemical British thermal unit delivered per second, used to quantify thermal energy flow.

What is a kilojoule/second in power measurement?

Kilojoule per second denotes the rate of energy transfer equal to 1,000 joules per second and is equivalent to a kilowatt.

Why convert from Btu (th)/second to kilojoule/second?

Conversion helps translate traditional thermal power ratings to a universal SI unit, enabling consistency with electrical and mechanical power measurements.
