Weight calculation from available length, width in mm and weight in micron for film

Can someone assist me in calculating weight from available length, width in mm and weight in micron for BOPP film?

I want to calculate weight of 650 meters roll BOPP film of 40 microns and 2 inches width.

You need to know the density of the film in grams per cubic centimeter. You also need to change all the units to a single unit (I'll use centimeters) and calculate the volume.
650 m = 65000 cm, 2" = 5.08 cm, and 40 µm = 0.004 cm. The volume of the tape is 65000 cm x 5.08 cm x 0.004 cm = 1321 cm³

Just multiply by the density and you will have the mass in grams.

Micron is an obsolete term for the micrometer, one-millionth of a meter, or one thousandth of a millimeter. 25.4 µm = 0.001 inches (1 mil).

In spite of being officially deprecated, it is used a lot.
