These calculators can be used to generate data using **density**, **radius** and **gravity**.

This alternate method of calculating gravity uses the solo gravity and charge field of the Earth
to work out the gravity for other bodies

Calculate the **gravity** given the **density** and **radius**.

g = E_{s}r/E_{r}+(E_{e}d^{2}r^{3})/(E_{d}^{2}E_{r}^{3})
