For the calculation of easting and northing from latitude and longitude, first calculate constants for the projection:
n = f / (2-f)
B = [a/(1+n)] (1 + n^2/4 + n^4/64)
h1 = n/2 ? (2/3)n^2 + (5/16)n^3 + (41/180)n^4
h2 = (13/48)n^2 ? (3/5)n^3 + (557/1440)n^4
h3 = (61/240)n^3 ? (103/140)n^4
h4 = (49561/161280)n^4
Then the meridional arc distance from equator to the projection origin (Mo) is computed from:
If LatO = 0 then Mo = 0
else if LatO ? 90°N ? ?/2 radians
Mo = B (?/2)
else if LatO ? 90°S ? -?/2 radians
Mo = B (-?/2)
else
Qo = asinh(tan LatO) ? [e atanh(e sin LatO)]
?o = atan(sinh Qo)
?O0 = asin (sin ?o)
Note: The previous two steps are taken from the generic calculation flow given below for latitude Lat, but here for LatO may be simplified to ?O0 = ?o = atan(sinh Qo).
?O1 = h1 sin(2?Oo)
?O2 = h2 sin(4?Oo)
?O3 = h3 sin(6?Oo)
?O4 = h4 sin(8?Oo)
?O = ?O0+ ?O1+ ?O2+ ?O3+ ?O4
Mo = B ?O
end
Note: if the projection grid origin is very close to the pole (within 2" or 50m), the tangent function in the equation for Qo is unstable and may fail. Mo may instead be calculated as:
Mo = a[(1 ? e^2/4 ? 3e^4/64 ? 5e^6/256 ?....)LatO ? (3e^2/8 + 3e^4/32 + 45e^6/1024+....)sin2LatO
+ (15e^4/256 + 45e^6/1024 +.....)sin4LatO ? (35e^6/3072 + ....)sin6LatO + .....]
with LatO in radians.
Then
Q = asinh(tan Lat) ? [e atanh(e sin Lat)]
? = atan(sinh Q)
?0 = atanh [cos ? sin(Lon ? LonO)]
?0 = asin (sin ? cosh ?0)
?1 = h1 sin(2?0) cosh(2?0)
?1 = h1 cos(2?0) sinh(2?0)
?2 = h2 sin(4?0) cosh(4?0)
?2 = h2 cos(4?0) sinh(4?0)
?3 = h3 sin(6?0) cosh(6?0)
?3 = h3 cos(6?0) sinh(6?0)
?4 = h4 sin(8?0) cosh(8?0)
?4 = h4 cos(8?0) sinh(8?0)
? = ?0 + ?1 + ?2 + ?3 + ?4
? = ?0 + ?1 + ?2 + ?3 + ?4
and
Easting, E = FE + ko B ?
Northing, N = FN + ko (B ? ? Mo)
For the reverse formulas to convert Easting and Northing projected coordinates to latitude and longitude first calculate constants of the projection where n is as for the forward conversion, as are B and Mo:
h1' = n/2 ? (2/3)n^2 + (37/96)n^3 ? (1/360)n^4
h2' = (1/48)n^2 + (1/15)n^3 ? (437/1440)n^4
h3' = (17/480)n^3 ? (37/840)n^4
h4' = (4397/161280)n^4
Then
?' = (E ? FE) / (B ko)
?' = [(N ? FN) + ko Mo] / (B ko)
?1' = h1' sin(2?') cosh(2?')
?1' = h1' cos(2?') sinh(2?')
?2' = h2' sin(4?') cosh(4?')
?2' = h2' cos(4?') sinh(4?')
?3' = h3' sin(6?') cosh(6?')
?3' = h3' cos(6?') sinh(6?')
?4' = h4' sin(8?') cosh(8?')
?4' = h4' cos(8?') sinh(8?')
?0' = ?' ? (?1' + ?2' + ?3' + ?4')
?0' = ?' ? (?1' + ?2' + ?3' + ?4')
?' = asin(sin ?0' / cosh ?0')
Q' = asinh(tan ?')
Q" = Q' + [e atanh(e tanh Q')] = Q' + [e atanh(e tanh Q")] which should be iterated until the change in Q" is insignificant. Then
Lat = atan(sinh Q")
Lon = LonO + asin(tanh(?0') / cos ?')

Since the natural origin may be at or near the centre of the projection and under normal coordinate circumstances would thus give rise to negative coordinates over parts of the mapped area, this origin is usually given false coordinates which are large enough to avoid this inconvenience. The False Easting, FE, is the value assigned to the abscissa (east or west) axis of the projection grid at the natural origin.
