  200 shells per â¦ carton. 600 cigarettes per pound so 16 ounces divided into that is .03 ounces per cigarette or 6 ounces per carton. so 0.6 ounces per pack so the shell weighing .4 to .5 ounces makes sense I guess. Metric scale to .001 ounce needed.
Bitumen is also frequently called tar or pitchâthough, properly speaking, tar is a byproduct of the carbonization of coal and pitch is actually obtained from the distillation of coal tar. Bitumen is defined by the U.S. Geological Survey as an extra-heavy oil with an API gravity less than 10Â° and a viscosity greater than 10,000 centipoise.
Naturally occurring asphalt/bitumen is sometimes specified by the term crude bitumen. Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil boiling at 525 Â°C (977 Â°F) is sometimes referred to as refined bitumen.n British English, the word 'asphalt' is used to refer to a mixture of mineral aggregate and asphalt/bitumen (also called tarmac in common parlance). The earlier word 'asphaltum' is now archaic and not commonly used. In American English, 'asphalt' is equivalent to the British 'bitumen'.
