About Converting Attonewtons to Nanonewtons
Attonewton and Nanonewton 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 nanonewton is 1e-9 newton units.
Formula
nanonewtons = attonewtons × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 attonewton equals 1e-18 base units, and 1 nanonewton equals 1e-9 base units, so dividing one by the other gives the direct attonewton-to-nanonewton factor of 1e-9.
Simple example
1 aN × 1e-9 = 1e-9 nN
1 attonewton = 1e-9 nanonewtons.
Real-world example
10 aN × 1e-9 = 1e-8 nN
10 attonewtons = 1e-8 nanonewtons.
