Dynamite is an absorbent mixture soaked in nitroglycerin then compacted into a cylindrical shape and wrapped in paper. TNT is a chemical compound called 2,4,6-trinitrotoluene. The energy density (joules/kilogram or J/kg) of dynamite is approximately 5 MJ/kg, compared to 4.0 MJ/kg of TNT (for TNT r.e.factor=1.00; for Nobel dynamite r.e. factor=1.25;). Dynamite is usually sold in the form of cylinders about 8 in (20 cm) long and about 1.25 in (3.2 cm) in diameter, with a weight of about 0.5 lb A stick of dynamite (0.19 kg, 75% nitroglycerin, no other explosives in the mixture of dynamite) contains roughly 1 MJ of energy.
