MBH is another way of expressing 1,000 British Thermal Units per Hour (BTU/hr). The M is the Roman numeral for "1,000" and the BH is a shortening of BTU/hr. This unit of measurement is often used to describe the weight of liquids used in the refrigeration industry. Since this unit is predominantly used in Great Britain, there may be a need to convert this measurement to the internationally recognizable ton. Knowing how to convert MBH to tons can prevent confusion when measurements are made so you can facilitate business transactions across international markets.
