About Converting Centimoles to Examoles
Centimole and Examole 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: Centimole is 0.01 mole units, and examole is 1000000000000000000 mole units.
Formula
examoles = centimoles × 1e-20
This factor comes from each unit's defined relationship to the category's base unit: 1 centimole equals 0.01 base units, and 1 examole equals 1e+18 base units, so dividing one by the other gives the direct centimole-to-examole factor of 1e-20.
Simple example
1 cmol × 1e-20 = 1e-20 Emol
1 centimole = 1e-20 examoles.
Real-world example
100 cmol × 1e-20 = 1e-18 Emol
100 centimoles = 1e-18 examoles.

Frequently asked questions
How many examoles are in 1 centimole?
1 centimole equals 1e-20 examoles, using the exact defined conversion factor rather than an estimate.
How do I convert centimole to examole?
Multiply the centimole value by 1e-20. The converter above does this instantly to whatever precision you set.
How do I convert examole back to centimole?
Use the reverse factor: 1 examole equals 1e+20 centimoles. You can also use the swap control in the converter above to flip the direction instantly.
What is a centimole?
Centimole (cmol) is a unit of chemistry.
What is a examole?
Examole (Emol) is a unit of chemistry.
Is the centimole to examole conversion exact?
Yes. Both centimole and examole are defined by fixed standards rather than physical artifacts, so the factor of 1e-20 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.
