Frequently Asked Questions
How do I convert Sierra Leone 1968 to WGS 84 coordinates?
Use the coordinate transformation tool above to convert Sierra Leone 1968 (EPSG:4175) to WGS 84 (EPSG:4326). Enter your source coordinates and click Transform. This uses the Geocentric translations (geog2D domain) method with 26m accuracy.
How do I transform Sierra Leone 1968 to WGS 84 using Proj4js?
Use proj4.defs to define both EPSG:4175 and EPSG:4326, then call proj4(source, target, [x, y]) to convert coordinates programmatically.
What is the accuracy of the Sierra Leone 1968 to WGS 84 transformation?
This transformation (EPSG:1614) has an accuracy of 26m using the Geocentric translations (geog2D domain) method. Area of use: Sierra Leone - onshore.
