What is kilogram-force (kgf)?

Kilogram-force is a gravitational unit of force defined as the force exerted by standard gravity on a mass of one kilogram, equal to 9.80665 newtons.

Why use micronewton (µN) as a unit?

Micronewton is an SI-derived unit used to measure extremely small forces, especially at micro- and nanoscale levels in engineering and biophysical applications.

How is the conversion from kgf to µN done?

The conversion multiplies the value in kilogram-force by 9,806,650 to get the equivalent force in micronewton.
