What does MBH stand for and where is it used?

MBH stands for one thousand British thermal units per hour. It is a non-SI unit mainly used in HVAC and heating equipment ratings in North America.

Why convert MBH to Btu (th)/second?

Converting MBH to Btu (th)/second expresses heat transfer rates in a smaller time unit, which is useful for precise HVAC system design and transient heat flow analysis.

Can this converter be used for industrial heating system calculations?

Yes, it is suitable for rating boilers, heat exchangers, and other heating equipment in industrial and building services applications.
