What does Btu (th)/hour measure?

Btu (th)/hour quantifies the rate at which heat energy is transferred, specifically one thermochemical British thermal unit per hour.

Where is metric horsepower commonly used?

Metric horsepower is often used to rate engine power in European and Asian markets, and to specify small industrial motors, pumps, and generators.

Can I use this conversion for mechanical engine efficiency?

No, this conversion only reflects ideal power equivalences and does not consider efficiency or losses in mechanical or thermal systems.
