Magnetic power converted to mechanical force

[Liam]

Is there a calculator on the web that would help a lay-man with no
engineering training (i.e. me) to convert, into mechanical units such as
pounds of force, the magnetic repulsion of two identical magnets for
each other at specificed distances (e.g. 1mm, 2mm, 5mm, 10mm, 15mm)? The
following data are available for the magnets: Gauss, coercive force and
intrinsic coercive force in oersteds, density, surface area, diameter,
inner diameter (if ring-shaped), thickness, and whether they are
anisotropic.

Thanks in advance.
