Make the notation
easier to check.

For Coordnote arithmetic corrections, feedback or privacy enquiries, email yardfill.helpful594@aleeas.com.

This is the verified existing public Yardfill forwarding alias, reused as the portfolio's shared inbox. It forwards through SimpleLogin to the owner. It is not a new or separate Coordnote mailbox. Include Coordnote in the subject; the owner's private mailbox address is not displayed here.

Use an illustrative pair

Include input format, an illustrative latitude/longitude pair, hemisphere choices, output precision and expected versus observed result. A copied report retains canonical fractions and input provenance, so check its contents before emailing. You do not need to share your actual location, identity documents, passwords or private files.

The worked notation guide explains sign conventions and model limits. Read Privacy for hosting and correspondence, or return to the converter. Using Coordnote requires no conversation or account.
