What does nanogram per liter (ng/L) measure?

Nanogram per liter measures ultra-trace amounts of a substance by mass concentration within one liter of fluid.

Where is grain per cubic foot (gr/ft³) commonly used?

Grain per cubic foot is typically used to quantify moisture content in air for HVAC calculations and to report airborne particulate concentrations in occupational and industrial environments.

Why is converting ng/L to gr/ft³ useful?

This conversion helps translate ultra-trace liquid mass concentrations into mass density units relevant for air quality and industrial ventilation assessments that rely on customary units.
