Is the milligrams per gallon to millimoles conversion exact?
The numeric factor shown (0.264172) is calculated from each unit's defined scale, but Milligrams per gallon and Millimoles belong to different chemistry measurement families (mass concentration vs amount of substance). A direct physical conversion between the two requires them to share the same measurement family; use this figure as a scale reference rather than a like-for-like chemical equivalence.
Where is the milligrams per gallon unit commonly used?
It is commonly used in chemistry, environmental testing, water quality analysis, pharmacology, and laboratory concentration reporting. Millimoles is typically used for amount of substance instead.

About this conversion
Milligrams per gallon and Millimoles are units used in the Universal Converter chemistry category. Milligram per Gallon (mg/gal): Mass concentration. Millimole (mmol): Millimole is 0.001 mole units.
Milligrams per gallon belongs to the mass concentration family, while Millimoles belongs to the amount of substance family. The chemistry converter is dimension-aware, so a direct conversion between units from different families is not chemically meaningful without extra context (such as a substance's molar mass or solution density); the scale factor above is provided purely for numeric reference.
