1 BTU/ft3 is approximately equal to __________ kcal/m3.

A 1

B 9

C 4

D 252

ANS:B - 9

To convert between British Thermal Units per cubic foot (BTU/ft³) and kilocalories per cubic meter (kcal/m³), we need to know the conversion factor between these two units. 1 BTU/ft³ is approximately equal to 9 kcal/m³. Therefore, the correct answer is 9.
