What does the poundal unit measure?

The poundal measures force in the foot–pound–second system, defined as the force needed to accelerate a one-pound mass at one foot per second squared.

Why use petagram to express mass?

Petagram is an SI mass unit used to quantify extremely large masses such as global carbon stocks and ice-sheet mass changes.

Can I convert poundal to petagram directly in all cases?

No, since poundal is force and petagram is mass, direct conversion requires context-specific assumptions about acceleration or environment.

What Is This Tool?

This tool converts poundals, a unit of force in the foot–pound–second system, into petagrams, an SI-derived unit of mass used for extremely large-scale measurements. It is useful for translating classical mechanics data into global mass inventories in scientific contexts.

How to Use This Tool?

Enter the value in poundals you want to convert
Select poundal as the 'from' unit and petagram as the 'to' unit
Click the convert button to see the equivalent mass in petagrams
Use the result to interpret forces in terms of large-scale masses when needed

Key Features

Converts poundal units of force to petagrams of mass
Supports interdisciplinary applications between FPS mechanics and geosciences
Provides precise conversion using the established formula
Browser-based and easy to use without installation
Useful for researchers dealing with legacy FPS data and global mass quantities

Examples

10 poundals equal 1.4086719565204e-13 petagrams
1000 poundals equal 1.4086719565204e-11 petagrams

Common Use Cases

Solving classical mechanics problems involving FPS units
Interpreting historic engineering or ballistics force data
Reporting global carbon stocks and emissions in petagrams of carbon
Estimating glacier or ice-sheet mass changes on a large scale
Reconciling FPS force measurements with SI mass inventories in research

Tips & Best Practices

Remember poundal measures force while petagram measures mass—ensure context justifies conversion
Use this tool to bridge data between FPS unit systems and modern SI mass units
Confirm the environmental or acceleration conditions when interpreting results
Apply conversion cautiously for interdisciplinary studies requiring compatibility of units

Limitations

Poundal is a force unit, petagram is mass—conversion assumes specific context or conditions
The small conversion factor means direct practical use is limited outside specialized analyses
Conversion may not reflect exact relationships without environmental assumptions
Not suitable for straightforward force-to-mass conversion in everyday scenarios
