What Is This Tool?
This unit converter transforms values from ton-force (long) [tonf (UK)], an imperial-era force unit based on the long ton weight, to petanewton [PT], an SI-derived unit used for extremely large forces. It serves users needing to bridge historical and astronomical force measurements.
How to Use This Tool?
-
Enter the value in ton-force (long) [tonf (UK)] you want to convert.
-
Select ton-force (long) [tonf (UK)] as the input unit and petanewton [PT] as the output unit.
-
Click the convert button to see the equivalent force in petanewtons.
-
Review and use the converted value for scientific or engineering applications.

Examples
-
Convert 10 ton-force (long) [tonf (UK)] to petanewton [PT]: 9.9640164181707e-11 PT
-
Convert 100 ton-force (long) [tonf (UK)] to petanewton [PT]: 9.9640164181707e-10 PT
Common Use Cases
-
Rating lifting or pressing capacities of older British machinery and presses.
-
Translating forces expressed in historical naval and shipbuilding documents.
-
Integrating legacy engineering data into modern scientific evaluations.
-
Assessing planetary- and stellar-scale forces in astrophysics and geophysics.
Tips & Best Practices
-
Use scientific notation to interpret very small numbers when converting to petanewtons.
-
Apply this conversion when dealing with large-scale force phenomena or astrophysical calculations.
-
Verify unit selections carefully to maintain accuracy in legacy to SI unit conversions.
Limitations
-
Ton-force (long) is a relatively small imperial force unit, leading to very small petanewton values.
-
Petanewtons are mostly relevant for extremely large force contexts, limiting everyday engineering use.
-
Different measurement scales mean careful attention is needed when interpreting converted results.
Frequently Asked Questions
-
What is ton-force (long) [tonf (UK)] used for?
-
It is used to express forces like lifting capacities of older British cranes and presses, as well as in historical engineering and naval documents.
-
When should I use petanewtons [PT]?
-
Petanewtons are appropriate for expressing extremely large forces encountered in planetary and astrophysical scale phenomena.
-
Why do converted values become very small?
-
Because ton-force (long) represents relatively small forces compared to the enormous magnitude of petanewtons, values shrink significantly in the conversion.
Key Terminology
-
Ton-force (long) [tonf (UK)]
-
An imperial-era unit of force equal to the weight of one long ton (2,240 pounds) under standard gravity, approximately 9,964 newtons.
-
Petanewton [PT]
-
An SI-derived force unit equal to 10^15 newtons, used for expressing extremely large forces in planetary and astrophysical contexts.
