Hi,
E-Tesla6 can calculate it very accurately. But it will assume there is at
least a vertical wire going to the toroid which does change the fields a
little from a theoretically perfect situation.
You can just specify the toroid as usual, but leave the rest of the parts
of the coil like 1 inch high so they don't matter.

I am not sure what you are trying to do with this number so there may be
details, but I can help with that.
Cheers,
Terry
