What is a kilogram-force (kgf)?

Kilogram-force is a unit of force based on the gravitational force exerted on a one-kilogram mass under standard gravity.

When should I use petanewton as a unit?

Petanewton is used to express immense forces found in planetary-scale and stellar phenomena.

Why are petanewton values so small when converting from kilogram-force?

Because petanewton measures very large forces, typical kilogram-force inputs convert into very small petanewton values.

Examples

10 kilogram-force [kgf] converts to 9.80665e-14 petanewton [PT].
1000 kilogram-force [kgf] converts to 9.80665e-12 petanewton [PT].

Common Use Cases

Interpreting older engineering specifications using kilogram-force for force values.
Converting mechanical load measurements into large-scale scientific units for comparison.
Analyzing forces in astrophysics, planetary science, and geophysics using SI units.

Tips & Best Practices

Always verify the context of force measurements when converting between units.
Use the converter for comparison or calculation of forces at very different scales.
Be mindful that kilogram-force depends on Earth's gravity, which may vary locally.

Limitations

Kilogram-force is a non-SI unit tied to Earth's gravity and varies by location.
Petanewton represents extremely large forces, so small-scale inputs produce tiny outputs.
Conversion is mostly theoretical or for specialized scientific fields involving large forces.
