About Converting Attonewtons to Nanonewtons
Attonewton and Nanonewton both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. 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
100 aN × 1e-9 = 1e-7 nN
100 attonewtons = 1e-7 nanonewtons.

Frequently asked questions
How many nanonewtons are in 1 attonewton?
1 attonewton equals 1e-9 nanonewtons, using the exact defined conversion factor rather than an estimate.
How do I convert attonewton to nanonewton?
Multiply the attonewton value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert nanonewton back to attonewton?
Use the reverse factor: 1 nanonewton equals 1,000,000,000 attonewtons. You can also use the swap control in the converter above to flip the direction instantly.
What is a attonewton?
Attonewton (aN) is a unit of engineering.
What is a nanonewton?
Nanonewton (nN) is a unit of engineering.
Is the attonewton to nanonewton conversion exact?
Yes. Both attonewton and nanonewton are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
