What does horsepower (water) measure?

Horsepower (water), also known as hydraulic horsepower, represents the mechanical power needed to move a volume of water against a head.

Why convert horsepower (water) to MBH?

Converting to MBH translates mechanical hydraulic power into thermal power units common in HVAC system design, helping coordinate equipment capacities.

No, MBH is a non-SI unit mainly used in North American HVAC applications to denote heating rates.
