Latitude and Longitude validator
Find coordinates by city, click the map, or validate latitude and longitude you already have.
How to use the Latitude and Longitude validator
What does the Latitude and Longitude validator do?
Check geographic coordinate pairs and convert between decimal and degrees-minutes-seconds notation; It applies this page-specific rule: latitude measures north or south of the equator from -90° to 90°.
Which inputs does this validator use?
To check geographic coordinate pairs and convert between decimal and degrees-minutes-seconds notation, enter Find a major city, Latitude Example: London's latitude is 51.5074, Longitude Example: London's longitude is -0.1278; keep every value in the same example; select Check coordinates when the values are ready; Start with a familiar case covered by this rule - The map is a quick visual coordinate picker rather than a street-level map - so the expected result can confirm the settings.
How should the validator result be read?
For a result intended to check geographic coordinate pairs and convert between decimal and degrees-minutes-seconds notation, the map is a quick visual coordinate picker rather than a street-level map; read longitude example: london's longitude is -0.1278 together with the original find a major city rather than as an isolated answer, and confirm that its units or structure match the intended use.
Which number comes first?
When the goal is to check geographic coordinate pairs and convert between decimal and degrees-minutes-seconds notation, latitude normally comes first, followed by longitude: 51.5074, -0.1278.
Can I search every address?
When using the page to check geographic coordinate pairs and convert between decimal and degrees-minutes-seconds notation, no.
Limits and accuracy
When using this validator to check geographic coordinate pairs and convert between decimal and degrees-minutes-seconds notation, latitude normally comes first, followed by longitude: 51.5074, -0.1278; a passing result confirms the rules tested on this page, but it does not prove that an address, identifier, account, or remote resource exists; keep find a major city until the output has been checked in its intended destination.
How latitude and longitude work
Latitude measures north or south of the equator from -90° to 90°. Longitude measures east or west of the prime meridian from -180° to 180°. A minus sign means south for latitude or west for longitude.
The map is a quick visual coordinate picker rather than a street-level map. City suggestions use a built-in list and the calculation stays in your browser.
