False easting 1000000.0 (one million meters)
Except for Geographics, all map projections (including both UTM and BC Albers) introduce distortion when representing features from the curved surface of the earth onto a flat map.
false easting
The linear value added to all x-coordinates of a map projection so that none of the values in the geographic region being mapped are negative.
False Easting, x coordinate of map(-projection) origin
y0
False Northing, y coordinate of map origin
k0, scale
Scale factor at central meridian [0.1, 10]
lam0
Central meridian, longitude of map origin (-180, 180)
phi0 ...
The first parameter is the false easting - a linear value applied to the origin of the x-coordinates - or the central meridian. The second parameter is the false northing - a linear value applied to the origin of the y-coordinates - or the equator.
By definition the Central Meridian is assigned a false easting of 500,000 meters. Any easting value greater than 500,000 meters indicates a point east of the central meridian.
WKT format shows the false eastings and northings in the projected unit (e.g. meters, feet) but in PROJ format it should always be given in meters.

Create a '.prj' file in ESRI format corresponding to the current location: ...
However, false eastings and false northings are frequently used, which effectively offset the origin to a different place on the coordinate plane. This is done in order to achieve several purposes: ...
UTM Zones
Eastings are measured from the central meridian (with a 500km false easting to insure positive coordinates). Northings are measured from the equator (with a 10,000km false northing for positions south of the equator).
UTM Zone 14 ...
Also, a false Easting value was chosen to provide FCS Easting values within the construction area which are different from Easting values of the ITM, UTM, or Gauss-Kruger projections used in Germany and Denmark.
If they are negative, you'll have to add a large offset to each value (creating a False Easting and False Northing). ArcGIS doesn't like negative numbers, and you'll get a "Warning: Inconsistent Extent" message if you try and open the XY coords.
[ESRI software] In ArcGIS, a parameter that offsets the z-origin from the surface of a vertical coordinate system. The vertical shift is similar in effect to the false easting or false northing parameters of a projected coordinate system.
All zones have their origin at the equator, use the meter as the system unit, and have a false easting of 500,000 meters and a false northing of 0. A scale reduction factor of 0.9996 is used on all zones.
designated 0 for quadrangles in the northern hemisphere, and 10,000,000 for quadrangles in the southern hemisphere. Since the distance from poles to Equator is approximately 10,000 km, such offset origins ensure coordinates (called false eastings ...
In our Data Frame Proeprties modify the coordinate system properties, Changing the False Easting to 0, and the False Northing to -143000. This basically shifts our coordinates closer to the origin.
Each zone has its own central meridian and false origin to the south and west of the zone. Coordinates are represented by the false easting and false northing measured in feet, followed by the state and zone.
A central meridian passes each zone and is given a false easting of 2 million feet. A false northing of 0 feet is established below the southern limit of each zone.
