About converting WGS 84 to S-JTSK / Krovak East North
Converting from WGS 84 (EPSG:4326) to S-JTSK / Krovak East-North (EPSG:5514) is the standard transformation for working with Czech and Slovak cadastral and federal mapping data. The Krovak East-North projection is a unique double-stereographic conic projection designed in 1922 specifically for the elongated NE-SW geometry of former Czechoslovakia.
The conversion involves both the Krovak projection and a datum shift from WGS 84 to S-JTSK on the Bessel 1841 ellipsoid. Helmert seven-parameter approximations give a few-decimetre accuracy across the country; the official ČÚZK grid transformation is more precise.

Frequently asked questions
- EPSG:5514 vs EPSG:5513 — which Krovak should I use?
- Both project to S-JTSK / Krovak. EPSG:5513 uses the old 'South, West' axis order; EPSG:5514 swaps to East, North to match modern GIS conventions. EPSG:5514 is preferred for new work.
- How accurate is converting WGS 84 to S-JTSK / Krovak East North?
- Projection-only conversions are accurate to floating-point precision. If a datum shift is involved, browser-based tools use Helmert parameters which are accurate to roughly 1-5 m; for surveying-grade work apply the official grid-shift 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.
