What Is This Tool?
This tool converts force values from piconewtons (pN), a unit used to express extremely small forces at the nanoscale, to gram-force (gf), a practical unit representing force exerted by one gram under standard gravity.
How to Use This Tool?
-
Enter the force value in piconewtons (pN) into the input field.
-
Select piconewton as the source unit and gram-force as the target unit.
-
Click the convert button to get the corresponding force in gram-force (gf).

Common Use Cases
-
Measuring molecular forces in single-molecule experiments.
-
Quantifying forces in nanoengineering devices such as MEMS/NEMS.
-
Specifying actuation forces for small mechanical components like tactile switches.
-
Translating nanoscale experimental forces into practical units for product testing.
Tips & Best Practices
-
Ensure input values are precise due to very small magnitudes involved.
-
Use this conversion to better communicate results between nanoscale experiments and engineering applications.
-
Double-check unit selections to avoid inaccuracies.
Limitations
-
Gram-force depends on standard gravity, which can vary slightly by location.
-
Converting piconewtons involves handling extremely small numbers, requiring accurate instruments and careful calculations.
Frequently Asked Questions
-
What does one piconewton represent?
-
One piconewton is an SI unit of force equal to 10 to the negative 12 newtons, mainly used to measure incredibly small forces at the nanoscale.
-
Why is the gram-force considered a non-SI unit?
-
Gram-force is not part of the International System of Units; it is based on the force exerted by a one-gram mass under standard gravity.
-
When would I need to convert from piconewton to gram-force?
-
Conversions are helpful when translating nanoscale force measurements into more practical force units for engineering design, product testing, or legacy systems.
