2. Projection parameters

Each zone is identical, just rotated 6° from its abutting neighbors.

Table F-2
Zone Parameters
λCM CM longitude varies; see Table F-1
SCM Scale along CM 0.9996
φo Origin latitude 00°00'00 (equator)
λo Origin longitude varies; see Table F-1
Xo False Easting 500,000 m
Yo False Northing N hemisphere: 0 m
S hemisphere: 10,000,000 m

Although zones are divided into 20 blocks, a point location is uniquely expressed as (X,Y) and Zone number with either a N (north hemisphere) or S (south) suffix.
