Coordinate Converter: Your go to tool for converting coordinates

Simple and fast to use

This coordinate converter switches between Decimal Degrees, Degrees Minutes Seconds, and UTM.

Enter one format and see all three right away.

The math runs in your browser for quick feedback.

Range checks catch errors early and keep values clean.

How It Works

Follow these steps to convert coordinates with confidence.

1. Choose Decimal Degrees, Degrees Minutes Seconds, or UTM in the menu.
2. Type your coordinates in the input field.
3. Select Convert to process your entry.
4. Read the results under each label.
5. Pick Clear to reset the form.

Input fields explained

• Format menu: Pick the format you currently have.
• Coordinate input: Enter your data in one of these ways.

• Decimal Degrees: Use latitude, longitude with a comma. Example "40.7128, -74.0060". Latitude stays between -90 and 90. Longitude stays between -180 and 180.
• Degrees Minutes Seconds: Use degrees, minutes, and seconds with N S E W. Example "40°42'46"N 74°00'22"W". You can use decimal seconds like "46.8" or "21.6". The letter can appear before or after the numbers.
• UTM: UTM means Universal Transverse Mercator. Use "zone easting northing hemisphere". Example "18 583960 4507523 N". Zone ranges from 1 to 60. Easting and northing are in meters. The hemisphere can be N or S. If you skip the hemisphere the tool uses N.

How to read your results

• Decimal Degrees: Shows latitude and longitude with six decimal places.
• Degrees Minutes Seconds: Shows degrees, minutes, and seconds with N S E W. Seconds show one decimal place.
• UTM: Shows zone, easting, northing, and hemisphere. Easting and northing round to whole meters.

Notes and limits

• Latitude stays within -90 to 90. Longitude stays within -180 to 180.
• UTM uses the WGS84 model for Earth.
• UTM zones run from 1 to 60. Use N or S for hemisphere.
• Southern hemisphere northing uses the standard 10000000 meter offset.
• Precision may drop near the poles and near zone edges.
• The tool supports Decimal Degrees, Degrees Minutes Seconds, and UTM. It does not support MGRS or UPS.
• Error messages guide fixes if the format needs changes.

Why You’ll Love It

This coordinate converter keeps work simple and clear.

You get instant results and plain labels for every format.

Use these tips to get the best results.

• Keep latitude first for every entry.
• Use a single space between latitude and longitude in Degrees Minutes Seconds.
• Paste values straight from a map or a GPS log.
• Add the hemisphere letter S for southern UTM data.
• Check zones for UTM projects that span wide areas.

Here are common ways people use this tool.

• Prep data for a Geographic Information System import.
• Share field points with teams that need a different format.
• Read drone image tags, then switch formats for reports.
• Plan hikes with Decimal Degrees, then print UTM for the trail.
• Teach map skills in class with quick format changes.
• Map property corners for a simple handoff to a surveyor.

A Quick Look at the Code

Here is what happens behind the scenes.

• The Decimal Degrees parser splits on a comma and checks ranges.
• The Degrees Minutes Seconds parser reads common patterns with N S E W.
• It supports decimal seconds for better precision.
• The UTM parser expects zone, easting, northing, and an optional hemisphere.
• Decimal Degrees output shows six decimals for fine location detail.
• Degrees Minutes Seconds output shows seconds to one decimal.
• UTM output rounds to the nearest meter for clear numbers.
• The math follows the WGS84 ellipsoid used by most maps.

The conversion writes all three formats at once for easy comparison.

Error handling keeps results clean and easy to trust.

Final Thoughts
