Frequently asked questions
How do I convert examoles to parts per million water?
Multiply the examoles value by 1×10^21 to get parts per million water. For example, 1 Emol = 1×10^21 ppm.
What is the formula for examoles to parts per million water?
Use the formula: value in ppm = value in Emol × 1×10^21. To convert back, value in Emol = value in ppm × 1×10^-21.
Is the examoles to parts per million water conversion exact?
The numeric factor shown (1×10^21) is calculated from each unit's defined scale, but Examoles and Parts per million water belong to different chemistry measurement families (amount of substance vs mass 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 examoles unit commonly used?
It is commonly used in chemistry and stoichiometry for expressing the amount of substance in a reaction or sample. Parts per million water is typically used for mass concentration instead.

About this conversion
Examoles and Parts per million water are units used in the Universal Converter chemistry category. Examole (Emol): Examole is 1000000000000000000 mole units. Parts per million water (ppm): Approximate mg/L in water.
Examoles belongs to the amount of substance family, while Parts per million water belongs to the mass 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.
