What is a petanewton used for?

A petanewton is an SI-derived force unit equal to 10^15 newtons, typically used to express extremely large forces such as those found in planetary or stellar-scale physics and geophysics.

Why convert petanewton to gram-force?

Conversion allows expressing very large planetary or stellar forces in units that correspond to very small, practical force measurements used in engineering and laboratory calibrations.

Is gram-force an SI unit?

No, gram-force is a non-SI unit defined as the force exerted by a mass of one gram under standard gravity, used mainly for small force measurements.
