How to Use This Calculator
Enter the requested values using the units shown. Keep all values consistent and review every assumption before interpreting the result.
Formula & Methodology
The calculator applies the displayed formulas directly to the entered values. Supporting outputs expose intermediate calculations rather than hiding them.
Worked example
For a 300 g racquet balanced at 32 cm with a 10 cm pivot, the balance-to-pivot distance is 22 cm before the moment calculation.
Real standardized swing-weight measurements may require a pendulum period, fixture-specific pivot and calibration. This is a simplified static estimate.
