What Is This Tool?
This tool converts force measurements from nanonewtons (nN), which quantify minuscule forces at the micro and nanoscale, into pound foot per square second, a force unit used in the foot–pound–second system where the pound is considered a mass unit.
How to Use This Tool?
-
Enter the force value in nanonewtons you wish to convert.
-
Select nanonewton as the input unit and pound foot per square second as the output unit.
-
Click convert to obtain the force value in pound foot/square second.
Key Features
-
Converts very small SI-derived force units (nanonewtons) into FPS force units (pound foot/square second).
-
Supports translation of forces for scientific, engineering, and educational purposes.
-
Offers conversions useful for legacy and microscale mechanical applications.
Examples
-
1 nanonewton equals 7.2330138512099e-9 pound foot per square second.
-
1000 nanonewtons equal 7.2330138512099e-6 pound foot per square second.
Common Use Cases
-
Calibration and reporting of MEMS force sensors and microactuators at small scales.
-
Quantifying tiny adhesion or contact forces between microscopic particles or cells.
-
Conducting mechanics problems and legacy calculations involving FPS units where pound is treated as mass.
Tips & Best Practices
-
Ensure consistent use of the pound as a mass unit to avoid confusion with pound-force units.
-
Pay close attention to numeric conversions due to the large magnitude differences between units.
-
Use this conversion for compatibility with older engineering documents or educational materials involving FPS mechanics.
Limitations
-
Significant difference in scale between nanonewtons and pound foot per square second may lead to numerical errors if not handled carefully.
-
Pound foot per square second is a specialist and legacy unit rarely used outside specific technical contexts.
-
Conversion assumes the pound represents mass (lbm) which can cause confusion with the pound-force (lbf) used in other systems.
Frequently Asked Questions
-
What is a nanonewton?
-
A nanonewton is an SI-derived unit of force equal to one billionth of a newton, used to measure very small forces at the micro and nanoscale.
-
What does pound foot per square second represent?
-
It is a force unit in the foot–pound–second system representing the force needed to accelerate one pound mass at one foot per second squared, also known as a poundal.
-
Why convert nanonewtons to pound foot per square second?
-
Conversion is useful for translating nanoscale forces into FPS units for legacy engineering calculations, educational purposes, or contexts requiring compatible imperial units.
Key Terminology
-
Nanonewton [nN]
-
An SI-derived force unit equal to 10^-9 newtons, used for measuring extremely small forces at micro and nanoscale.
-
Pound foot per square second
-
A force unit in the FPS system equal to one pound mass accelerated at one foot per second squared, also known as the poundal.
-
FPS system
-
A system of units that uses foot, pound, and second as base measurements, where pound can denote mass instead of force.
