Use this page to get latitude and longitude of a place. You just have to move the map. When the cross at the center is over the place that you want, read the lat lng
coordinates indicated below the map.
You also get timezone and current time
for that place.
By using the search box to zoom the map to some city you get the corresponding lat/long coordinates as well. If you know the coordinates of a place, you can also insert them in the search box and the map will show you where that place is (for this to work the latitude/longitude coordinates must be in the same format as the coordinates shown below the map on this page).
If you need a map to locate a place for specific coordinates that you already know, but they are in a different format, try instead this latitude longitude finder
