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

Solo gravity is the part of what we now call gravity that is based solely on the radius. The other part of gravity is the charge field which works against solo gravity and is based on density.

For more information you can read read this paper by Miles Mathis.

Calculate the **gravity** given the **radius**.

g = E_{s}r/E_{r}

Calculate the **radius** given the **gravity**.

r = gE_{r}/E_{g}
