Frequently asked questions
How do I convert milligrams per gallon to millimoles per liter?
Multiply the milligrams per gallon value by 0.000264 to get millimoles per liter. For example, 1 mg/gal = 0.000264 mmol/L.
What is the formula for milligrams per gallon to millimoles per liter?
Use the formula: value in mmol/L = value in mg/gal × 0.000264. To convert back, value in mg/gal = value in mmol/L × 3785.411784.
Is the milligrams per gallon to millimoles per liter conversion exact?
The numeric factor shown (0.000264) is calculated from each unit's defined scale, but Milligrams per gallon and Millimoles per liter belong to different chemistry measurement families (mass concentration vs molar concentration). 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 per liter is typically used for molar concentration instead.

About this conversion
Milligrams per gallon and Millimoles per liter are units used in the Universal Converter chemistry category. Milligram per Gallon (mg/gal): Mass concentration. Millimole per liter (mmol/L): Millimolar concentration.
Milligrams per gallon belongs to the mass concentration family, while Millimoles per liter belongs to the molar concentration 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.
