About Converting Petamoles to Zettamoles
Petamole and Zettamole 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 zettamole is 1e+21 mole units.
Formula
zettamoles = petamoles × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 petamole equals 1e+15 base units, and 1 zettamole equals 1e+21 base units, so dividing one by the other gives the direct petamole-to-zettamole factor of 0.000001.
Simple example
1 Pmol × 0.000001 = 0.000001 Zmol
1 petamole = 0.000001 zettamoles.
Real-world example
100 Pmol × 0.000001 = 0.0001 Zmol
100 petamoles = 0.0001 zettamoles.
Conversion table
| Petamole (Pmol) | Zettamole (Zmol) |
|---|---|
| 0.001 Pmol | 1e-9 Zmol |
| 0.01 Pmol | 1e-8 Zmol |
| 0.1 Pmol | 1e-7 Zmol |
| 1 Pmol | 0.000001 Zmol |

Reverse conversion: Zettamole to Petamole
0.000001 Zmol × 1000000 = 1 Pmol
0.000001 zettamoles = 1 petamole.
petamoles = zettamoles × 1000000

Frequently asked questions
How many zettamoles are in 1 petamole?
1 petamole equals 0.000001 zettamoles, using the exact defined conversion factor rather than an estimate.
How do I convert petamole to zettamole?
Multiply the petamole value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert zettamole back to petamole?
Use the reverse factor: 1 zettamole equals 1,000,000 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 zettamole?
Zettamole (Zmol) is a unit of chemistry.
Is the petamole to zettamole conversion exact?
Yes. Both petamole and zettamole are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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.
