What does Btu (th)/minute measure?

It measures the rate of thermal energy transfer, specifically one thermochemical British thermal unit per minute, used mainly in heating or cooling capacity contexts.

Why convert Btu (th)/minute to joule per second?

Converting to joule per second standardizes power measurements into the SI system, enabling easier comparison and integration with electrical and mechanical power units.

Are there any limitations when converting these units?

Yes, the conversion depends on using the thermochemical Btu definition and slight variations or rounding errors may arise, especially in precise scientific work.
