Convert Femtomole to Mole (fmol to mol)

Femtomole (fmol) and Mole (mol) are both units of amount of substance. With the conversion form below, you can effortlessly and accurately convert femtomole to mole. This free online calculator tool makes it simple and easy to perform the conversion from fmol unit to the mol unit.

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.

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.

A mole (symbol: mol) is the SI base unit of amount of substance. Moles are used to measure the quantity of elementary entities, such as atoms, molecules, ions, electrons, or other specified particles. Since 2019, one mole has been defined as containing exactly 6.02214076 × 10²³ specified elementary entities, a fixed value known as the Avogadro constant.

The mole provides a practical way to relate the microscopic world of atoms and molecules to measurable laboratory quantities. Instead of counting individual particles, scientists use moles to calculate chemical reactions, prepare solutions, determine concentrations, and express the amount of substances involved in physical and chemical processes.

The mole is fundamental to chemistry, biochemistry, pharmacy, materials science, environmental science, and chemical engineering. It is also the basis for SI-prefixed units such as kilomole (kmol), millimole (mmol), micromole (µmol), nanomole (nmol), picomole (pmol), femtomole (fmol), and attomole (amol), making it one of the most important units in scientific measurement.
