About Converting Petamoles to Moles

Petamole and Mole both measure mass concentration — how much of a substance is dissolved or dispersed in a given volume — a core calculation for preparing lab solutions, checking water quality against a regulatory limit, or formulating a pharmaceutical dose. Specifically: Petamole is 1000000000000000 mole units, and mole is the SI amount of substance unit.

Formula

moles = petamoles × 1e+15

This factor comes from each unit's defined relationship to the category's base unit: 1 petamole equals 1e+15 base units, and 1 mole equals 1 base unit, so dividing one by the other gives the direct petamole-to-mole factor of 1e+15.

Simple example

1 Pmol × 1e+15 = 1e+15 mol

1 petamole = 1e+15 moles.

Real-world example

100 Pmol × 1e+15 = 1e+17 mol

100 petamoles = 1e+17 moles.

Reverse conversion: Mole to Petamole

1e+15 mol × 1e-15 = 1 Pmol

1e+15 moles = 1 petamole.

petamoles = moles × 1e-15

Understanding the Petamole (Pmol)

Petamole is 1000000000000000 mole units.

Understanding the Mole

Mole (mol) measures amount of substance. The SI base unit of amount of substance, defined since 2019 by fixing the Avogadro constant at exactly 6.02214076 × 10²³ per mole. It is classified as a SI base unit.

Where it's used: Universal — SI base unit used worldwide

Uses of the Mole today

  • Chemical reaction stoichiometry
  • Solution concentration (molarity) calculations
  • Gas law calculations in chemistry and physics

History of the Mole

The mole was introduced as a practical chemistry unit in the early 20th century and adopted as an SI base unit in 1971. It was originally defined via the number of atoms in 12 grams of carbon-12; the 2019 SI redefinition instead fixed the Avogadro constant to an exact value, so the mole no longer depends on a physical reference sample.

Historical origin. Mole was not the invention of a single named person; it developed through the process described above.

Frequently asked questions

How many moles are in 1 petamole?

1 petamole equals 1e+15 moles, using the exact defined conversion factor rather than an estimate.

How do I convert petamole to mole?

Multiply the petamole value by 1e+15. The converter above does this instantly to whatever precision you set.

How do I convert mole back to petamole?

Use the reverse factor: 1 mole equals 1e-15 petamoles. You can also use the swap control in the converter above to flip the direction instantly.

What is a petamole?

Petamole (Pmol) is a unit of chemistry.

What is a mole?

Mole (mol) measures amount of substance. The SI base unit of amount of substance, defined since 2019 by fixing the Avogadro constant at exactly 6.02214076 × 10²³ per mole. It is classified as a SI base unit.

Is the petamole to mole conversion exact?

Yes. The SI base unit of amount of substance, defined since 2019 by fixing the Avogadro constant at exactly 6.02214076 × 10²³ per mole. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.

What's the difference between mass concentration and molarity?

Mass concentration expresses how much mass of a substance is present per unit volume (for example, grams per liter). Molarity expresses the amount in moles per liter instead, which accounts for the substance's molecular weight. This category converts mass-concentration units.
