*gurgle* I was hoping to stick to short Python functions. Thanks for

Hi Mike,
It's essentially a table look-up. It's explained in detail in the DMA
Tech Manual. However, there is a fairly clean C implementation for
doing this with Geotrans -- a calculator for converting geographic
coordinates that's pretty nifty in its own right. They also have a
module for USNG, which is very similar.

I'm trying to understand how to convert between lat/lon, UTM, and
MGRS.
UTM is a piece of cake, but MGRS is confusing. I'm looking at the
wikipedia
article, and I don't understand how to reliably determine the
SQ_ID, "FJ" in
the example here:

What's the process for determining those 100km square areas?
