Micronewton [µN]
Micronewton is a very small unit of force in the International System of Units (SI).
1 micronewton (µN) equals 10−6 newtons (0.000001 newton).
It is used to measure extremely small forces in fields like microelectronics, nanotechnology, and sensitive scientific experiments.
To put it in perspective:
1 µN=0.000001 N
Micronewtons allow precise quantification of tiny forces that are beyond the sensitivity of larger units like millinewtons.
