About Converting Petanewtons to Millinewtons
Petanewton and Millinewton 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 millinewton is 0.001 newton units.
Formula
millinewtons = petanewtons × 1e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 petanewton equals 1e+15 base units, and 1 millinewton equals 0.001 base units, so dividing one by the other gives the direct petanewton-to-millinewton factor of 1e+18.
Simple example
1 PN × 1e+18 = 1e+18 mN
1 petanewton = 1e+18 millinewtons.
Real-world example
10 PN × 1e+18 = 1e+19 mN
10 petanewtons = 1e+19 millinewtons.
