How to Convert pmol to fmol

Use this pmol to fmol converter to change picomoles into femtomoles. Type a picomole value and get femtomoles at once.

Pico- is 10−12 and femto- is 10−15. One picomole is 1,000 femtomoles, so multiply by 1,000.

For example, 0.5 pmol × 1,000 = 500 fmol.

1 pmol = 1,000 fmolMultiply the number of picomoles by 1,000 to get femtomoles.

Conversion Formula

The formula to convert pmol to fmol is:

fmol = pmol × 1,000

Where:

  • pmol = amount in picomoles (10⁻¹² mol)
  • fmol = amount in femtomoles (10⁻¹⁵ mol)
Example Calculation33 pmol × 1,000 = 33,000 fmol

Unit Definitions

What is a picomole (pmol)?

A picomole (pmol) is a unit of amount of substance equal to 10⁻¹² mole.

The prefix pico- (p) means 10⁻¹², or one trillionth. So 1 pmol = 0.000000000001 mol.

What is a femtomole (fmol)?

A femtomole (fmol) is a unit of amount of substance equal to 10⁻¹⁵ mole.

The prefix femto- (f) means 10⁻¹⁵, or one quadrillionth. So 1 fmol = 0.000000000000001 mol.

Why Is the Conversion Factor 1,000?

A picomole is 10⁻¹² mole, while a femtomole is 10⁻¹⁵ mole.

1 pmol = 10⁻¹² mol1 fmol = 10⁻¹⁵ mol
10⁻¹² ÷ 10⁻¹⁵ = 10³ = 1,000

Therefore, 1 picomole equals 1,000 femtomoles. To convert pmol to fmol, you multiply by 1,000, and to convert fmol to pmol, you divide by 1,000.

Uses and Importance of pmol and fmol

Picomoles and femtomoles are both used for tiny amounts. Moving between them keeps numbers in a range people can read without errors.

Loading mass spectrometers

A peptide standard prepared at a few pmol per µL is often loaded as a few hundred fmol.

Cloning

DNA insert and vector amounts for ligation are often expressed in fmol, while stock concentrations may be worked out in pmol.

Sequencing libraries

Library amounts can be expressed in fmol when pooling small volumes of concentrated libraries.

Frequently Asked Questions (FAQ)

How many fmol are in 1 pmol?

1 pmol = 1,000 fmol.

What is 0.05 pmol in fmol?

0.05 × 1,000 = 50 fmol.

How many molecules are in 0.5 pmol?

About 3.011 × 1011 molecules. That is 500 fmol, and each femtomole holds about 602 million molecules.

Is femtomole the smallest unit people use?

No. Attomoles (10−18 mol) and zeptomoles (10−21 mol) are also used in some very sensitive methods.

Do I need molecular weight for pmol to fmol?

No. Only the prefix changes.
