Useful Info: Torque (in N*m) = 9.55 * Power (in watts) / Speed (in rpm)
1N*m = 141.61 oz*in = 8.85 lb*in = 10,200.0 g*cm, 1.0 hp = 745.7 watts
1.0 in = 2.54 cm, 1.0 kg = 2.205 lb = 35.27 oz, 1.0 mile = 1.61 Km, Tc=(Tf-32)*5/9

20'/ft Container Volume: 33cbm/1170cft (internal: 5.9m x 2.35m x 2.39m)
40'/ft Container Volume: 67cbm/2385cft (internal: 12.0m x 2.35 x 2.39m)
Air Shipping Volume to Weight Conversion Formula: [L(cm) * W(cm) * H(cm)]/6000 => Kgs
