Heat unit conversion

Power unit conversion table: Unit: Watt (W), Kilogram-force·meter/second (kgf·m/s), Calorie/second (cal/s), Metric horsepower (hp), British thermal unit per hour (Btu/h). Watt (W): 19.80665, 0.2388, 1.36*10^-3, 3.412; Kilogram-force·meter/second (kgf·m/s): 0.10197, 0.0243, 1.39*10^-4, 0.348; Calorie/second (cal/s): 4.18684, 1.0581, 5.69*10^-3, 14.285; Metric horsepower (hp): 735.4997, 212.781, 175.641, 2509.52; British thermal unit per hour (Btu/h): 0.29307, 12.874, 0.0703, 3.99*10^-4. Volume unit conversion table: Volume unit conversions: Cubic meter (m3), Liter (L, dm3), Cubic centimeter (cm3, ml, C.C.), Cubic foot (ft3), Cubic inch (in3). Cubic meter (m3): 1, 1000, 10^6, 35.3147, 147.6102, 37×10^4; Liter (L, dm3): 10^-3, 1, 1000, 35.3147, 147×10^-2, 1.0237; Cubic centimeter (cm3, ml, C.C.): 10^-6, 10^-3, 1, 35.3147, 147×10^-5, 6.10237×10^-2; Cubic foot (ft3): 2.83168×10^-3, 28.3168, 2.83168×10^4, 11728; Cubic inch (in3): 1.63871×10^-5, 1.63871×10^-2, 16.3871, 5.78704×10^-4. I calculated it myself as follows: Since m3/w = 1 m3 / 1 W = 35.3147 ft3 / 3.412 Btu/h = 10.35 ft3/Btu/h, then 4.8 m3/w = 50 ft3/Btu/h. Therefore, 4.8 m3/w = 50,000 ft3/1000 Btu/h. I’m not sure about this result; I’m waiting for experts to explain it
