How to Convert fmol to Attomole?
Converting from fmol to Attomole is a straightforward process. Follow these steps to ensure accurate conversions from femtomole to attomole:
- Select the Femtomole Value: Start by determining the femtomole (fmol) value you want to convert into attomole (Attomole). This is your starting point.
- Multiply by the Conversion Factor: To calculate femtomole to equivalent attomole amount, multiply the selected fmol value by 1000.
- Illustration of Multiplication:
- 1 fmol = 1000 Attomole
- 10 fmol = 10000 Attomole
- 100 fmol = 100000 Attomole
- Find the Conversion Result: The result of this multiplication is your converted value in attomole unit. This represents the same amount-of-substance but in a different unit.
- Save Your Attomole Value: After converting, remember to save the result. This value represents the amount-of-substance you initially measured, now expressed in attomoles.
- Alternative Method – Division: If you prefer not to multiply, you can achieve the same conversion by dividing the femtomole value by 0.001. This alternative method also gives you the correct amount-of-substance in attomoles.
- Illustration of Division:
- Attomole = fmol ÷ 0.001
What is Amount of Substance?
Amount of substance is an SI base quantity that counts the number of specified elementary entities—atoms, molecules, ions, electrons, or other particles—in a sample. Its unit is the mole (mol). One mole contains exactly 6.02214076 × 10²³ entities (Avogadro's number), defined exactly since the 2019 SI revision. The mole is the bridge between the atomic scale and the laboratory scale, making it indispensable in chemistry and biochemistry.
What is Femtomole?
A femtomole (fmol) is an SI-prefixed unit of amount of substance equal to 10−15 mole. The prefix femto- denotes one quadrillionth (0.000000000000001) of the base unit. Although extremely small, femtomoles are routinely measured in analytical chemistry, molecular biology, biochemistry, pharmaceutical research, and clinical laboratories where only tiny quantities of molecules are present.
Like all decimal multiples of the mole, the femtomole follows the International System of Units (SI). Since one mole contains exactly 6.02214076 × 1023 specified elementary entities, one femtomole corresponds to approximately 6.022 × 108 atoms, molecules, ions, or other elementary entities, depending on the substance being measured.
Femtomoles are commonly used in DNA sequencing, protein analysis, mass spectrometry, chromatography, immunoassays, and trace chemical analysis. Expressing extremely small quantities in femtomoles makes laboratory measurements easier to interpret than using very small decimal values of moles.
What is Attomole?
An attomole (amol) is an SI-prefixed unit of amount of substance equal to 10−18 mole. The prefix atto- represents one quintillionth (0.000000000000000001) of the base unit. Although extremely small, the attomole is a practical unit in analytical chemistry, molecular biology, biochemistry, nanotechnology, and pharmaceutical research, where scientists often measure minute quantities of molecules, DNA, proteins, or other chemical substances.
Like all metric submultiples of the mole, the attomole follows the International System of Units (SI). Since one mole contains exactly 6.02214076 × 1023 specified elementary entities, one attomole corresponds to approximately 6.022 × 105 particles, depending on the type of entity being counted, such as atoms, molecules, or ions.
Attomoles are commonly encountered in highly sensitive laboratory techniques such as mass spectrometry, fluorescence assays, DNA sequencing, proteomics, and trace chemical analysis. Using attomoles allows researchers to express extremely small amounts of substances without writing long decimal values in moles.

Femtomole to Attomole Examples
Example 1:
Convert 0.3 Femtomole amount-of-substance to Attomole unit.
Solution:
We know that one Femtomole is equivalent to 1000 Attomole.
Therefore,
0.3 fmol = 0.3 x 1000 Attomole.
0.3 fmol = 300 Attomole.
Hence, 0.3 Femtomole is approximately equal to 300 Attomole.
Example 2:
