What is the calorie (IT) unit used for?

The calorie (IT) is a historical energy unit originally used in thermodynamics and steam-engine calculations to measure heat energy.

Why is pound-force foot used for both energy and torque?

Pound-force foot has the same dimensional units for energy and torque; while commonly used for mechanical work and impact energies, it is also used for torque, though these represent different physical quantities.

Can this converter be used for modern scientific measurements?

This converter is designed primarily for legacy data and engineering contexts; modern scientific work generally uses the joule and may require more precise unit definitions.
