About Converting Petamoles to Attomoles
Petamole and Attomole 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 attomole is 1e-18 mole units.
Formula
attomoles = petamoles × 1e+33
This factor comes from each unit's defined relationship to the category's base unit: 1 petamole equals 1e+15 base units, and 1 attomole equals 1e-18 base units, so dividing one by the other gives the direct petamole-to-attomole factor of 1e+33.
Simple example
1 Pmol × 1e+33 = 1e+33 amol
1 petamole = 1e+33 attomoles.
Real-world example
100 Pmol × 1e+33 = 1e+35 amol
100 petamoles = 1e+35 attomoles.

Reverse conversion: Attomole to Petamole
1e+33 amol × 1e-33 = 1 Pmol
1e+33 attomoles = 1 petamole.
petamoles = attomoles × 1e-33

Frequently asked questions
How many attomoles are in 1 petamole?
1 petamole equals 1e+33 attomoles, using the exact defined conversion factor rather than an estimate.
How do I convert petamole to attomole?
Multiply the petamole value by 1e+33. The converter above does this instantly to whatever precision you set.
How do I convert attomole back to petamole?
Use the reverse factor: 1 attomole equals 1e-33 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 attomole?
Attomole (amol) is a unit of chemistry.
Is the petamole to attomole conversion exact?
Yes. Both petamole and attomole are defined by fixed standards rather than physical artifacts, so the factor of 1e+33 used above is exact to as many digits as you choose to display.
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.
