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

About this conversion
Petamoles and Parts per billion water are units used in the Universal Converter chemistry category. Petamole (Pmol): Petamole is 1000000000000000 mole units. Parts per billion water (ppb): Approximate ug/L in water.
Petamoles belongs to the amount of substance family, while Parts per billion 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.
