Free Survey and Coordinate Tools
Free calculators for surveyors, engineers and landowners: coordinates on a map, DMS and UTM converters, distance and bearing, plot area, slope, and land area and length units. They work in your browser, with no sign-up.
Coordinates
- Coordinates on a mapClick the map, search a place or use your location to get its latitude and longitude, degrees-minutes-seconds, UTM zone and easting/northing, with a Google Maps link.Use the tool About it
- DMS ↔ decimal degreesConvert degrees, minutes and seconds such as 25°11'35"N to decimal degrees and back — one value or a whole list pasted from Excel.Use the tool About it
- Lat/long ↔ UTMConvert latitude and longitude to UTM easting, northing and zone on WGS 84, or UTM back to latitude and longitude. The zone is worked out for you.Use the tool About it
Measure
- Distance and bearingThe distance and bearing between two points from latitude and longitude on the WGS 84 ellipsoid, or from eastings and northings on a grid — plus the point at a given bearing and distance.Use the tool About it
- Plot area from coordinatesPaste the corners of a plot as eastings and northings or latitude and longitude and get its area in m², hectares, acres, kanal and marla, with the perimeter.Use the tool About it
- Slope and gradientWork out a slope from rise and run, or convert between percent grade, degrees and 1 in N — for roads, drains, ramps and roofs.Use the tool About it
Convert units
- Land area unitsConvert land and floor areas between square metres, square feet, acres, hectares, kanal, marla, feddan, dunam, guntha and cents.Use the tool About it
- Length unitsConvert lengths between metres, feet, US survey feet, yards, miles, nautical miles, chains, links, rods, karam and gaz.Use the tool About it
