What does a poundal measure?

A poundal measures force in the foot–pound–second system, specifically the force needed to accelerate one pound mass by one foot per second squared.

How is a pound different from a poundal?

A pound is a unit of mass used in the avoirdupois system, while a poundal is a unit of force in the FPS system.

Why convert from poundal to pound?

Users convert to translate FPS force units into mass units common in everyday contexts such as shipping or body weight reporting.

Key Features

Converts poundal (force) units to pound (mass) units accurately using a fixed conversion rate.
Browser-based and easy to use with quick input and selection options.
Supports understanding and translating between FPS force units and customary mass units.

Examples

5 poundals equals approximately 0.1553 pounds.
10 poundals correspond to about 0.3106 pounds.

Common Use Cases

Solving classical mechanics problems involving forces in the FPS system.
Reading and interpreting engineering or ballistics texts that utilize FPS units.
Converting older force measurements into mass units for retail, shipping, or health data alignment.

Tips & Best Practices

Be aware that poundal measures force while pound measures mass; understand the physical context before converting.
Use this conversion mainly for theoretical or interpretative purposes between force and mass units.
Double-check unit selections to avoid confusion in practical applications.

Limitations

Direct conversion between force (poundal) and mass (pound) requires careful consideration of physical meaning.
Conversion assumes standard gravity conditions and is primarily theoretical rather than for direct weight measurement.
