Why is the conversion factor between gram/cubic millimeter and grain/cubic foot so large?

Because gram/cubic millimeter measures mass per a very small volume and grain/cubic foot per a much larger volume, the factor reflects this difference in scale.

Can I use grain/cubic foot for scientific high-precision measurements?

Grain per cubic foot is a customary unit that is less precise than SI units, so it might not be suitable for all high-precision applications.

What industries commonly use this conversion?

Industries such as microfabrication, material science, HVAC engineering, indoor air quality monitoring, and occupational safety use this conversion.
