About Converting Petanewtons to Exanewtons
Petanewton and Exanewton both measure force, and the conversion matters whenever an SI-trained engineer needs to compare notes with a US-trained one, or vice versa. Specifically: Petanewton is 1000000000000000 newton units, and exanewton is 1000000000000000000 newton units.
Formula
exanewtons = petanewtons × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 petanewton equals 1e+15 base units, and 1 exanewton equals 1e+18 base units, so dividing one by the other gives the direct petanewton-to-exanewton factor of 0.001.
Simple example
1 PN × 0.001 = 0.001 EN
1 petanewton = 0.001 exanewtons.
Real-world example
10 PN × 0.001 = 0.01 EN
10 petanewtons = 0.01 exanewtons.
