About Converting Yoctomoles to Attomoles
Yoctomole 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: Yoctomole is 1e-24 mole units, and attomole is 1e-18 mole units.
Formula
attomoles = yoctomoles × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 yoctomole equals 1e-24 base units, and 1 attomole equals 1e-18 base units, so dividing one by the other gives the direct yoctomole-to-attomole factor of 0.000001.
Simple example
1 ymol × 0.000001 = 0.000001 amol
1 yoctomole = 0.000001 attomoles.
Real-world example
100 ymol × 0.000001 = 0.0001 amol
100 yoctomoles = 0.0001 attomoles.
Conversion table

Reverse conversion: Attomole to Yoctomole
0.000001 amol × 1000000 = 1 ymol
0.000001 attomoles = 1 yoctomoles.
yoctomoles = attomoles × 1000000

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