Frequently asked questions
How do I convert grams per gallon to millimoles per liter?
Multiply the grams per gallon value by 0.264172 to get millimoles per liter. For example, 1 g/gal = 0.264172 mmol/L.
What is the formula for grams per gallon to millimoles per liter?
Use the formula: value in mmol/L = value in g/gal × 0.264172. To convert back, value in g/gal = value in mmol/L × 3.785412.
Is the grams per gallon to millimoles per liter conversion exact?
The numeric factor shown (0.264172) is calculated from each unit's defined scale, but Grams 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 grams 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
Grams per gallon and Millimoles per liter are units used in the Universal Converter chemistry category. Gram per Gallon (g/gal): Mass concentration. Millimole per liter (mmol/L): Millimolar concentration.
Grams 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.
