WGS 84 → UPS

Latitude and longitude to UPS converter

Convert polar latitude and longitude to UPS individually or in batches, with supported latitude ranges, hemisphere and coordinate-order guidance.

Batch coordinate converter

Enter one WGS 84 coordinate per line as latitude, longitude.

Input example: 85, 0

0 of 100 coordinates

Results use: easting, northing | hemisphere=[hemisphere]

Output example: 2000000, 1444542.609 | hemisphere=north

Numeric coordinates are rounded for display: decimal latitude/longitude to up to 6 decimal places, metre-based coordinates to up to 3, DMS seconds to up to 2, and DDM minutes to up to 4.

About this conversion

Convert WGS 84 positions in the polar caps to Universal Polar Stereographic eastings and northings.

Frequently asked questions

What input is accepted?

By default, enter WGS 84 latitude first and longitude second in decimal degrees. Select Reverse coordinate order to enter longitude first. Latitude must be from −90 to 90 and longitude from −180 to 180.

What output will I receive?

The result contains hemisphere, easting and northing in metres in the WGS 84 UPS grid.

Which axes and units are used?

WGS 84 input defaults to latitude then longitude in degrees. UPS output uses easting then northing in metres with the derived hemisphere.

How are precision and datum handled?

UPS is a projection, not a precision upgrade. At 84°N and 80°S, both UTM and UPS are valid, so use the system required by your workflow.

Where can I use this coordinate system?

UPS supports 84°N through 90°N and 80°S through 90°S, including both poles. UTM and UPS both accept the boundary parallels.

What should I check?

  • Use input positions within the supported north or south polar range.
  • Check that the selected latitude/longitude order matches each row.
  • Use numeric UPS for polar work rather than unsupported UPS-style MGRS text.

When should I use UPS instead of UTM?

Use UPS from 84°N to the North Pole or from 80°S to the South Pole. Both systems accept the boundary parallels.

Is the pole itself supported?

Yes. UPS is specifically designed to cover the poles.
