Indian systems included
Kalianpur 1880, 1937 and 1975, the India zone grids, UTM zones 42N to 47N on both WGS 84 and Indian datums, and the WGS 84 state systems.
Convert UTM to Latitude and Longitude
Convert UTM easting and northing to WGS 84 latitude and longitude. Zones 42N to 47N cover all of India. One point or a pasted column, converted in your browser.
Why this matters here
Older Indian survey and revenue records sit on the Everest spheroid, not WGS 84. Treating one as the other puts everything a few hundred metres out — enough to move a plot boundary onto a neighbour.
Bulk paste
Paste a column straight out of a spreadsheet. Anything after the first two values is carried through as a label, and the result downloads as CSV.
Nothing leaves your device
The arithmetic runs in your browser with proj4. No coordinate is transmitted, logged or stored anywhere.
Frequently asked questions
Which coordinate systems are supported?
WGS 84 and Web Mercator, UTM zones 42N to 47N on both WGS 84 and Indian datums, the Kalianpur India zone grids, and the WGS 84 state systems including Maharashtra. Each is listed with its EPSG code so you can check it against your source.
How accurate is the datum shift?
Transformations use the standard seven-parameter shifts published for each datum. Between Everest-based Indian datums and WGS 84 the difference is a few hundred metres, so using the wrong one is immediately obvious on the map preview.
Can I convert a whole list at once?
Yes. Switch to the bulk tab and paste a column. Comma, tab, semicolon or space separated all work, and anything after the first two values is kept as a label. Download the result as CSV.
Which value goes in which box?
Easting or longitude on the left, northing or latitude on the right. The labels change with the system you pick, so you never have to remember. Bulk mode has a swap option.
Is anything uploaded?
No. Everything runs in your browser using proj4, so no coordinate ever leaves your device.
