What does Btu (th)/hour measure?

Btu (th)/hour quantifies the rate of heat transfer equivalent to one thermochemical British thermal unit per hour, often used in HVAC and heating applications.

When should I use calorie (IT)/second?

Calorie (IT)/second is used mainly in laboratory calorimetry and historical contexts where heat-transfer rates are expressed using the International Table calorie.

Is this conversion suitable for modern engineering?

While useful for specific cases, calorie (IT)/second units are less common today, and SI units like watts are typically preferred in contemporary engineering fields.
