About Converting Exanewtons to Attonewtons
Exanewton and Attonewton 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: Exanewton is 1000000000000000000 newton units, and attonewton is 1e-18 newton units.
Formula
attonewtons = exanewtons × 1e+36
This factor comes from each unit's defined relationship to the category's base unit: 1 exanewton equals 1e+18 base units, and 1 attonewton equals 1e-18 base units, so dividing one by the other gives the direct exanewton-to-attonewton factor of 1e+36.
Simple example
1 EN × 1e+36 = 1e+36 aN
1 exanewton = 1e+36 attonewtons.
Real-world example
10 EN × 1e+36 = 1e+37 aN
10 exanewtons = 1e+37 attonewtons.
