About Converting Petanewtons to Newtons
Petanewton and Newton 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: Petanewton is 1000000000000000 newton units, and the newton is the SI unit of force.
Formula
newtons = petanewtons × 1e+15
This factor comes from each unit's defined relationship to the category's base unit: 1 petanewton equals 1e+15 base units, and 1 newton equals 1 base unit, so dividing one by the other gives the direct petanewton-to-newton factor of 1e+15.
Simple example
1 PN × 1e+15 = 1e+15 N
1 petanewton = 1e+15 newtons.
Real-world example
100 PN × 1e+15 = 1e+17 N
100 petanewtons = 1e+17 newtons.
Conversion table
| Petanewton (PN) | Newton (N) |
|---|---|
| 1 PN | 1e+15 N |
| 10 PN | 1e+16 N |
| 50 PN | 5e+16 N |
| 100 PN | 1e+17 N |
| 500 PN | 5e+17 N |
| 1,000 PN | 1e+18 N |
Reverse conversion: Newton to Petanewton
1e+15 N × 1e-15 = 1 PN
1e+15 newtons = 1 petanewton.
petanewtons = newtons × 1e-15

Understanding the Petanewton (PN)
Petanewton is 1000000000000000 newton units.
Understanding the Newton
Newton (N) measures force. The newton is the SI derived unit of force: the force needed to accelerate a 1 kg mass at 1 meter per second squared. It is classified as a SI derived unit.
Where it's used: Standard scientific and engineering force unit worldwide
Uses of the Newton today
- Physics and engineering force calculations
- Material strength and structural engineering specifications
- Product specifications (e.g. spring force, adhesive strength)
History of the Newton
The newton is named after Isaac Newton in recognition of his laws of motion, which define the relationship between force, mass, and acceleration that the unit embodies. It was formally adopted as the SI derived unit of force as part of the broader 20th-century SI system.
Historical origin. Newton was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many newtons are in 1 petanewton?
1 petanewton equals 1e+15 newtons, using the exact defined conversion factor rather than an estimate.
How do I convert petanewton to newton?
Multiply the petanewton value by 1e+15. The converter above does this instantly to whatever precision you set.
How do I convert newton back to petanewton?
Use the reverse factor: 1 newton equals 1e-15 petanewtons. You can also use the swap control in the converter above to flip the direction instantly.
What is a petanewton?
Petanewton (PN) is a unit of engineering.
What is a newton?
Newton (N) measures force. The newton is the SI derived unit of force: the force needed to accelerate a 1 kg mass at 1 meter per second squared. It is classified as a SI derived unit.
Is the petanewton to newton conversion exact?
Yes. Both petanewton and newton are defined by fixed standards rather than physical artifacts, so the factor of 1e+15 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.
