About Converting Nanonewtons to Attonewtons
Nanonewton 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: Nanonewton is 1e-9 newton units, and attonewton is 1e-18 newton units.
Formula
attonewtons = nanonewtons × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 nanonewton equals 1e-9 base units, and 1 attonewton equals 1e-18 base units, so dividing one by the other gives the direct nanonewton-to-attonewton factor of 1000000000.
Simple example
1 nN × 1000000000 = 1,000,000,000 aN
1 nanonewton = 1,000,000,000 attonewtons.
Real-world example
10 nN × 1000000000 = 10,000,000,000 aN
10 nanonewtons = 10,000,000,000 attonewtons.
