Bearing & Distance from Coordinates is a free bearing between coordinates for surveyors, civil engineers and property buyers โ instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Bearing & Distance from Coordinates
Inverse computation: bearing and distance between two E,N coordinate pairs. The calculation implements d = โ(ฮEยฒ+ฮNยฒ); ฮธ = atan2(ฮE, ฮN) (COGO โ coordinate geometry). atan2(ฮE, ฮN) โ easting FIRST โ lands the bearing in the right quadrant automatically. Setting-out lists for site pegs come straight from this 'inverse' calc.

Frequently asked questions
What formula does the Bearing & Distance from Coordinates use?+
It computes d = โ(ฮEยฒ+ฮNยฒ); ฮธ = atan2(ฮE, ฮN), per COGO โ coordinate geometry. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
atan2(ฮE, ฮN) โ easting FIRST โ lands the bearing in the right quadrant automatically. Setting-out lists for site pegs come straight from this 'inverse' calc.
Are regional land units exact?+
Conversion factors follow state revenue-department values noted on the tool. Units like bigha and katha vary by region, so always confirm the local factor named in your land records.
Is the Bearing & Distance from Coordinates free to use?+
Yes โ completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
