WebCurrently, magnetic north is roughly north of Hudson Bay in Canada. The difference between magnetic north and true north is “magnetic declination.” In the continental U.S., declination can vary from nearly 20 degrees east in places on the West Coast to nearly 20 degrees west in places on the East Coast. WebThe formula for calculating grid convergence (sometimes called meridian convergence) for spherical UTM projections was given (very incorrectly until just now) at How to Calculate North? In case that is not clear γ = arctan [tan (λ - λ 0) × sin φ] where γ is grid convergence, λ 0 is longitude of UTM zone's central meridian,
