About Converting Attonewtons to Exanewtons
Attonewton 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: Attonewton is 1e-18 newton units, and exanewton is 1000000000000000000 newton units.
Formula
exanewtons = attonewtons × 1e-36
This factor comes from each unit's defined relationship to the category's base unit: 1 attonewton equals 1e-18 base units, and 1 exanewton equals 1e+18 base units, so dividing one by the other gives the direct attonewton-to-exanewton factor of 1e-36.
Simple example
1 aN × 1e-36 = 1e-36 EN
1 attonewton = 1e-36 exanewtons.
Real-world example
10 aN × 1e-36 = 1e-35 EN
10 attonewtons = 1e-35 exanewtons.
