Convert gram-force to petanewton
Please provide values below to convert gram-force [gf] to petanewton [PT], or Convert petanewton to gram-force.
1 gf = 9.8067e-18 PT. To convert gram-force to petanewton, multiply the value by 9.8067e-18; to go the other way, divide by it (1 PT = 1.0197e+17 gf). Both units measure force and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 gf = 9.8067e-18 PT

Gram-Force
Gram-force (gf) is a unit of force defined as the force exerted by one gram of mass in standard gravity, approximately equal to 0.00980665 newtons.
History/Origin
The gram-force originated in the late 19th and early 20th centuries as part of the centimeter-gram-second (CGS) system of units, used to express forces in terms of grams and centimeters. It was commonly used in physics and engineering before the adoption of the SI system.
Current Use
Gram-force is now largely obsolete and replaced by the SI unit newton (N) in scientific and technical contexts. However, it may still be used in some engineering fields, calibration, and for illustrative purposes in educational settings.
Petanewton
A petanewton (PT) is a unit of force equal to 10^15 newtons, used for measuring extremely large forces.
History/Origin
The petanewton was introduced as part of the SI prefixes to facilitate the expression of very large forces, although it is rarely used in practical applications due to the scale of forces involved.
Current Use
The petanewton is primarily used in scientific contexts involving large-scale forces, such as astrophysics and cosmology, but remains a theoretical unit with limited practical application.
