Stoichiometry
Pick out the wrong unit conversion of heat transfer rate.

1 BTU/ft².hr = 2.712 kcal/m².hr
1 kcal/hr= 1.163 Watt
1 Watt = 1.163 kcal/hr
1 kcal/m².hr = 0.3687 BTU/ft².hr = 1.163 Watt/m²

Stoichiometry
Pick out the wrong unit conversion of temperature.

Temperature difference of 1°K = 1°C = 9/5 °F
°C = (F- 32) x 0.555
°R = 273 + °F
°F = (°C + 17.778) x 1.8
