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

1 kcal/m2.hr.°C = 0.2048 BTU/ft2.hr. °F. = 1.163 W/m2.°K
1 kcal/m2.hr.°K = 1.163 W/m2.°C
1 W/m2 . °C = 0.1761 BTU/ft2.hr.°F.
1 BTU/ft2.hr.°F = 4.88 kcal/m2.hr.°C = 20.44 kJ/m2.hr°C = 5.678 W/m2.°C.

Correct Answer: 1 kcal/m2.hr.°K = 1.163 W/m2.°C
