Official EPSG transformation from Kertau (RSO) to WGS 84

The EPSG Geodetic Parameter Dataset defines 1 transformation between Kertau (RSO) (EPSG:4751) and WGS 84 (EPSG:4326). Its parameters, accuracy and area of use are listed below.

Kertau (RSO) to WGS 84 (1)

EPSG:8659±15 m
Method:
Concatenated operation
Area of use:
Asia - Malaysia (west) and Singapore
Scope:
Transformation of MRT68 RSO coordinates.
  1. Kertau (RSO) to Kertau 1968 (1) (null)
  2. Kertau 1968 to WGS 84 (1) (null)

Step 1 is necessary to rescale the grid units before using step 2.

Frequently asked questions

How accurate is converting Kertau (RSO) to WGS 84?
The most accurate official EPSG transformation between these systems is accurate to about ±15 m within its stated area of use. Browser-based converters approximate datum shifts with Helmert parameters; for surveying-grade work apply the official transformation in a desktop GIS.
Does my data leave the browser when I use this converter?
No. All coordinate transformations are computed locally in your browser using proj4js. The coordinates you enter are never transmitted to any server.
