About Converting Attomoles to Picomoles
Attomole and Picomole 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: Attomole is 1e-18 mole units, and picomole is 1e-12 mole units.
Formula
picomoles = attomoles × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 attomole equals 1e-18 base units, and 1 picomole equals 1e-12 base units, so dividing one by the other gives the direct attomole-to-picomole factor of 0.000001.
Simple example
1 amol × 0.000001 = 0.000001 pmol
1 attomole = 0.000001 picomoles.
Real-world example
100 amol × 0.000001 = 0.0001 pmol
100 attomoles = 0.0001 picomoles.

Reverse conversion: Picomole to Attomole
0.000001 pmol × 1000000 = 1 amol
0.000001 picomoles = 1 attomoles.
attomoles = picomoles × 1000000

Frequently asked questions
How many picomoles are in 1 attomole?
1 attomole equals 0.000001 picomoles, using the exact defined conversion factor rather than an estimate.
How do I convert attomole to picomole?
Multiply the attomole value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert picomole back to attomole?
Use the reverse factor: 1 picomole equals 1,000,000 attomoles. You can also use the swap control in the converter above to flip the direction instantly.
What is a attomole?
Attomole (amol) is a unit of chemistry.
What is a picomole?
Picomole (pmol) is a unit of chemistry.
Is the attomole to picomole conversion exact?
Yes. Both attomole and picomole 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.
