Frequently Asked Questions
-
What does grain per cubic foot measure?
-
It measures mass density as the number of grains per cubic foot of volume, used especially in HVAC and industrial air-quality applications.
-
Why convert grain/cubic foot to milligram/cubic millimeter?
-
Converting to milligram/cubic millimeter allows translating legacy and macro-scale density values into units suitable for microscale biomedical and material science uses.

Key Terminology
-
Grain/cubic foot [gr/ft³]
-
A customary unit of mass density equal to one grain (64.79891 mg) of mass per one cubic foot of volume, used commonly in HVAC and industrial ventilation.
-
Milligram/cubic millimeter [mg/mm³]
-
A density unit describing mass in milligrams divided by volume in cubic millimeters, equivalent to 1 g/cm³, typically used for microscale density measurements.
-
Density
-
A measurement of mass per unit volume, commonly used to quantify how compact a substance or material is.
