How many grams in powder is 100 millimeters?

Answer 1

A millimetre is a measure of distance while a gram is a measure of mass. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.

The mass of powder will depend on how thickly it is laid out.

Answer 2

There is no direct conversion between grams and millimeters as they measure different properties (grams measure mass, while millimeters measure length). To determine the grams in a powder, you need to know the density of the powder, which is usually given in grams per milliliter (g/mL) or grams per cubic centimeter (g/cm³). You would then multiply the density by the volume in millimeters (100 mL) to find the mass in grams.
