FAQ
What is the conversion factor from gf to kN?
1 gf equals 9.80665e-6 kN. To convert, multiply the value in grams-force by 9.80665e-6.
How do I convert 1 gf to kN?
1 gf = 9.80665e-6 kN. For any value, multiply by 9.80665e-6.
How do I convert kN back to gf?
Divide by the same factor — or equivalently, multiply by 101971.6. So 1 kN = 101972 gf.
When would I need to convert gram-force to kilonewton?
Force conversions between gf and kN are needed in structural analysis, mechanical equipment design, lifting and rigging calculations, and load specification. Newtons and kilonewtons are standard in SI-based structural codes; pound-force and kips are common in US codes and vendor datasheets.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
