What does grain/gallon (US) measure?

It measures density by representing mass in grains per one U.S. liquid gallon, commonly used in water hardness reporting.

Why convert grain/gallon (US) to picogram/liter?

To translate traditional water hardness or concentration units into ultra-trace metric measurements suitable for environmental or clinical analysis.

Are conversion results affected by temperature or pressure?

This conversion assumes a standard U.S. gallon volume without factoring in temperature or pressure changes.
