What is ounce-force (ozf)?

Ounce-force is a non-SI unit of force equal to one sixteenth of a pound-force, representing the weight of an avoirdupois ounce under standard gravity.

How is pound foot per square second defined?

It is a unit of force in the foot–pound–second system equal to the force needed to accelerate a 1 lb mass at 1 ft/s², also known as the poundal.

When should I convert from ounce-force to pound foot/square second?

When translating small force measurements in everyday or hobby settings into units compatible with mechanical calculations in the FPS system.

What Is This Tool?

This converter allows you to translate force values from ounce-force (ozf), a small-scale non-SI unit of force, into pound foot per square second, a unit from the foot–pound–second system treating the pound as mass.

How to Use This Tool?

Enter the force value in ounce-force [ozf]
Select ounce-force as the input unit
Choose pound foot/square second as the output unit
Click convert to see the equivalent force value

Key Features

Converts small force measurements from ounce-force to pound foot/square second
Supports legacy and small-scale mechanical applications
Based on established conversion rate and formula
Browser-based and easy to use for mechanical engineering and hobby contexts

Examples

5 ozf converts to approximately 10.05439 pound foot/square second
0.5 ozf converts to about 1.00544 pound foot/square second

Common Use Cases

Specifying small actuation forces for switches or buttons
Rating forces on small springs, clips, or latches
Translating legacy force values from hobby, postal, or packaging contexts
Solving textbook mechanics problems with FPS units
Reviewing historical engineering documents using imperial units
Performing small-scale dynamics or ballistic estimates in FPS system

Tips & Best Practices

Ensure consistent unit systems when converting between force units
Use this tool for small force values where ounce-force is applicable
Be aware that ounce-force depends on standard gravity while pound foot/square second uses mass-based definitions
Double-check conversions in contexts requiring precise mechanical calculations

Limitations

Ounce-force is a non-SI unit linked to standard gravity assumptions
Pound foot/square second treats pound as a mass unit rather than weight
Care is needed to maintain consistency in unit definitions to avoid calculation errors
