What is a femtonewton?

A femtonewton is an extremely small unit of force equal to 10^-15 newtons, used to measure forces at molecular and nanoscale levels.

What does one dyne represent?

One dyne is the CGS unit of force needed to accelerate a mass of one gram by one centimetre per second squared, equivalent to 10⁻⁵ newtons.

Why convert femtonewtons to dynes?

Converting femtonewtons to dynes helps express tiny molecular forces in CGS units commonly used in classical physics and historical data.

Key Features

Converts femtonewton (fN), a unit for very small forces, to dyne (dyn), a CGS unit of force.
Facilitates comparison of molecular forces with classical physics and legacy CGS-based data.
Browser-based and easy to use for scientific and engineering applications involving force measurement.

Examples

5 femtonewton [fN] converts to 5 × 1e-10 dyne = 5e-10 dyne [dyn].
100 femtonewton [fN] converts to 100 × 1e-10 dyne = 1e-8 dyne [dyn].

Common Use Cases

Analyzing biomolecular interactions and forces smaller than piconewtons in molecular biology.
Calculating optical forces and radiation pressure on nanoparticles in optical trapping experiments.
Reporting small forces in laboratory physics or classical mechanics problems using CGS units.
Interpreting historical physics or astrophysics data that employs the CGS system.

Tips & Best Practices

Ensure unit awareness when converting between modern SI units and legacy CGS units to avoid confusion.
Use this conversion for comparing molecular-scale forces with classical physics data expressed in dynes.
Be mindful of very small decimal results due to the tiny magnitude of femtonewtons when converted to dynes.

Limitations

The extremely small values resulting from this conversion can lead to precision challenges in calculations.
The dyne unit in the CGS system is less common in modern SI measurement contexts, which may require careful communication.
