What does 1 Btu (th)/second represent?

It is a unit of power measuring the rate of heat transfer equal to one thermochemical British thermal unit delivered per second.

Why convert Btu (th)/second to calorie (th)/hour?

This conversion allows expressing heat transfer rates at smaller scales or in laboratory settings where calorie-based units are more common.

Is calorie (th)/hour commonly used today?

It is less common, with the watt preferred in modern applications, but it remains relevant in specialized or legacy fields.
