What is a millinewton?

A millinewton (mN) is an SI unit of force equal to one thousandth of a newton, used for measuring very small forces such as those in micro-actuators or tactile sensors.

Why would I convert millinewtons to petanewtons?

Conversion to petanewtons helps express very small forces in a common SI framework for comparing them with extremely large forces encountered in planetary and stellar physics.

Are there any issues when converting millinewtons to petanewtons?

Yes, the resulting values can be extremely small, possibly causing underflow or reduced significance in numerical computations.
