Address to Coordinates
Enter decimal latitude and longitude (WGS84) to generate the corresponding UTM zone, easting, and northing.
WARNING: Datum Shift Risk
Coordinate systems matter! Mixing WGS84 and local datums (like Tokyo Datum or NAD27) without converting causes physical errors of up to 450 meters (1,500 feet). Always double-check your map's assumed datum before use in the field.
UTM Result (WGS84)
Quick Reference
UTM Format: Zone + Letter + Easting + Northing (e.g., 51S 377561 4621522)
Example: 40.7128N, -74.0060W = 18T 584384 4509355
Pro Tip: Each UTM zone is 6 wide. Crossing zone boundaries without recomputing causes 554km errors in autonomous systems.

Warning: Verify Your Calculation
Coordinate accuracy varies by device and datum. Do not use these results for legal or construction purposes without checking:
GPS Accuracy Alert
Your phone's GPS can be off by 30 meters. This can cause critical errors in your data.
Check My Accuracy →Datum Shift Risk
Using the wrong coordinate system (e.g. WGS84 vs NAD83) creates a permanent 1-meter offset.

The WGS84 vs. NAD83 Dilemma
Most beginners assume that all latitude/longitude coordinates are the same. However, in North America, the difference between the WGS84 (used by GPS) and NAD83 (used for local surveying) can result in a physical shift of up to 1 meter. For high-precision construction projects, failing to account for this "datum shift" can lead to catastrophic misalignment of foundations or property boundaries.
Coordinate Drift Over Time
Tectonic plate movement means that your physical location on Earth is constantly moving relative to the GPS satellite network. In regions like Australia, this drift is significant enough that coordinate reference systems must be updated periodically. Our tools utilize the most stable geodetic algorithms to ensure that your conversions remain mathematically sound across different epochs.
