Which unit is used to express appliance input calculations in the examples?

• A. MBtu
• B. Btuh
• C. kW
• D. Btu

Answer: (B)

Expressing appliance input as a rate of energy use. Appliance input calculations show how much energy the appliance consumes per hour, so the unit used should be BTU per hour. Btuh is BTU per hour, which directly conveys the energy flow rate required by the appliance. The unit Btu alone measures energy, not the rate, so it doesn’t specify how quickly energy is used. MBtu represents a much larger energy amount (million BTU) and isn’t typical for individual appliance input. Kilowatts are another way to express power, but the examples in this context use Btuh, which aligns with common gas appliance specifications. Therefore, Btuh is the unit used to express appliance input calculations in the examples.
