To convert from volume to mass, you need to know the density of the paper from which the tube is constructed. Tyler Shailesh wrote back
Shailesh, If you sliced the tube from end to end and rolled it out flat you would have a rectangular piece of paper 14 mm long and width the circumference of the tube. The circumference of a circle is π times the diameter so the rectangular sheet of paper would have an area of
Since there are 1,000 millimeters in a meter there are 1,000,000 square millimeters in a square meter. Hence the rectangular sheet of paper would have an area of
at 180 grams per square meter that's
If you have other tubes and the dimensions are in millimeters and grams per square meter then the procedure to calculate the weight of the tube is as follows:
I hope this helps,
