Frequently Asked Questions
Why is my Lat/Long output slightly off compared to Google Maps?
Google Maps displays coordinates on the WGS84 ellipsoid (EPSG:4326) while rendering raster tiles in Web Mercator (EPSG:3857). If your coordinate originates from a regional datum (such as NAD27 or Tokyo Datum), an explicit datum shift must be calculated. Coordinate Converter calculates pure mathematical WGS84/GRS80 transformations.
How large can my CSV file be in the Batch Converter?
Our client-side processing engine easily handles datasets up to 50,000 rows in modern browsers using Web Workers. Because files never leave your device, memory limits are dictated solely by your local device RAM.
My coordinates were auto-detected incorrectly.
Ensure your input does not contain non-printable formatting characters, tabs, or trailing punctuation. If using decimal degrees, do not append direction letters (e.g. use -74.006 instead of -74.006W).
