How to Convert fM to Attomolar?
Converting from fM to Attomolar is a straightforward process. Follow these steps to ensure accurate conversions from femtomolar to attomolar:
- Select the Femtomolar Value: Start by determining the femtomolar (fM) value you want to convert into attomolar (Attomolar). This is your starting point.
- Multiply by the Conversion Factor: To calculate femtomolar to equivalent attomolar amount, multiply the selected fM value by 1000.
- Illustration of Multiplication:
- 1 fM = 1000 Attomolar
- 10 fM = 10000 Attomolar
- 100 fM = 100000 Attomolar
- Find the Conversion Result: The result of this multiplication is your converted value in attomolar unit. This represents the same molar-concentration but in a different unit.
- Save Your Attomolar Value: After converting, remember to save the result. This value represents the molar-concentration you initially measured, now expressed in attomolars.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the femtomolar value by 0.001. This alternative method also gives you the correct molar-concentration in attomolars.
- Illustration of Division:
- Attomolar = fm ÷ 0.001
What is Molar Concentration?
Molar concentration (also called molarity) expresses the amount of a solute dissolved per unit volume of solution. Its SI unit is mol/m³, but the most widely used practical unit is mol/L (moles per litre), also written as M or mol·L⁻¹. For example, a 1 M (one molar) solution of sodium chloride contains 1 mole of NaCl dissolved in enough water to make 1 litre of solution. Molar concentration is the primary way of expressing solution strength in chemistry, biology, and medicine.
What is Femtomolar?
Femtomolar (symbol: fM) is a metric unit of molar concentration equal to one quadrillionth of a mole per liter (10-15 mol/L). It is commonly used in molecular biology, immunology, biochemistry, and analytical chemistry to express extremely dilute solutions.
This converter follows the internationally accepted SI prefix relationship, where 1 femtomolar = 10-15 moles per liter (mol/L). Reference: NIST Guide to the SI – Prefixes for Multiples and Submultiples of SI Units.
What is Attomolar?
Attomolar (symbol: aM) is a metric unit of molar concentration equal to one quintillionth of a mole per liter (10-18 mol/L). Attomolar is used to express extremely low concentrations in analytical chemistry, molecular biology, nanotechnology, and biomedical research.
This converter follows the internationally accepted SI prefix relationship, where 1 attomolar = 10-18 moles per liter (mol/L). Reference: NIST Guide to the SI – Prefixes for Multiples and Submultiples of SI Units.

Femtomolar to Attomolar Examples
Example 1:
Convert 0.4 Femtomolar molar-concentration to Attomolar unit.
Solution:
We know that one Femtomolar is equivalent to 1000 Attomolar.
Therefore,
0.4 fM = 0.4 x 1000 Attomolar.
0.4 fM = 400 Attomolar.
Hence, 0.4 Femtomolar is approximately equal to 400 Attomolar.
Example 2:
Convert 3 Femtomolar molar-concentration to Attomolar unit.
Solution:
We know that one Femtomolar is equivalent to 1000 Attomolar.
Therefore,
3 fM = 3 x 1000 Attomolar.
3 fM = 3000 Attomolar.
Hence, 3 Femtomolar is approximately equal to 3000 Attomolar.
