What is kilogram-force (kgf)?

Kilogram-force is a non-SI gravitational unit of force defined as the force exerted by standard gravity on one kilogram of mass.

When is femtonewton (fN) used?

Femtonewton units quantify extremely small forces encountered in molecular-scale measurement and nanoscale scientific experiments.

Why convert from kilogram-force to femtonewton?

Converting allows translating macroscopic force values into the extremely small forces essential for fields like molecular biology, nanotechnology, and precision instrumentation.
