How this is calculated

Your browser reports a latitude, a longitude and an accuracy in metres. MDN defines the accuracy as a radius at 95% confidence. The page shows the numbers two ways, and converts typed values either way.

  1. Decimal degrees are shown to 5 decimal places, latitude first.
  2. For degrees, minutes and seconds: degrees = the whole part of the value; minutes = the whole part of (the remainder × 60); seconds = the rest of that remainder × 60. One degree is 60 minutes and one minute is 60 seconds by definition. The page works in hundredths of a second as whole numbers, so seconds are rounded to 2 decimals without floating-point noise, and a seconds value that rounds to 60.00 carries into the next minute. The hemisphere letter comes from the sign.
  3. For degrees, minutes and seconds to decimal: the sign (S and W negative) times (degrees + minutes ÷ 60 + seconds ÷ 3,600), rounded to 5 decimals. Minutes and seconds must be at least 0 and below 60.
  4. Accuracy is shown in metres and in feet, where feet = metres ÷ 0.3048.

Fill in either decimal degrees or degrees, minutes and seconds, not both. Everything is computed in your browser and nothing is sent anywhere. The Copy buttons use your browser's clipboard and nothing else.

What latitude and longitude are

Latitude and longitude are angles that name a point on the Earth's surface. Latitude says how far north or south of the equator the point is, from -90 at the South Pole to 90 at the North Pole. Longitude says how far east or west of the prime meridian it is, from -180 to 180. Together they give a position that works anywhere, which is why a phone can report one without knowing any place names.

Two formats, one position

Decimal degrees write each angle as one number, such as 30.26720. Degrees, minutes and seconds split the same angle into three parts, as in 30°16′1.92″N. They describe the same point. Maps and apps usually take decimal degrees, while older documents and some charts use degrees, minutes and seconds. Negative numbers mean south or west in decimal form, and the letters N, S, E and W do the same job in the other.

The two formats round differently, so converting one way and back can change the last digit.

Watch the order

This page and most map apps write latitude first, then longitude. Some mapping and GIS tools expect longitude first. Pasting a pair into the wrong order puts the point somewhere else entirely, and a latitude over 90 is an immediate sign that the two are swapped. The page rejects values outside the allowed ranges rather than reinterpret them.

Your accuracy radius is on the card next to the numbers. A position quoted to 5 decimals can still be wrong by far more than its last digit suggests, so read the two together. Why your location may be wrong lists the usual reasons.
