Stoichiometry
Pick out the wrong unit conversion of heat transfer co-efficient.

1 BTU/ft².hr.°F = 4.88 kcal/m².hr.°C = 20.44 kJ/m².hr°C = 5.678 W/m².°C

1 W/m² . °C = 0.1761 BTU/ft².hr.°F

1 kcal/m².hr.°K = 1.163 W/m².°C

1 kcal/m².hr.°C = 0.2048 BTU/ft².hr. °F. = 1.163 W/m².°K

1 BTU/ft².hr.°F = 4.88 kcal/m².hr.°C = 20.44 kJ/m².hr°C = 5.678 W/m².°C
