A BTU/hr.ft.2 °F is equal to

A 1 kcal/hr. m2°C.

B 4.88 kcal/hr. m.2°C.

C 1 kcal/hr. m2.°K.

D none of these.

ANS:B - 4.88 kcal/hr. m.2°C.

A BTU/hr.ft.2 °F (British Thermal Unit per hour per square foot per degree Fahrenheit) is equal to 1 kcal/hr.m2°C (kilocalorie per hour per square meter per degree Celsius). Therefore, the correct option is: 1 kcal/hr.m2°C.
