Bearing Between Points Calculator
Find the clockwise bearing between two points where X increases east and Y increases north.
A QUICK WALKTHROUGH
How to use this tool
- Enter the start and end X/Y coordinates.
- Optionally enter an explicit east-positive magnetic declination.
- Review true bearing, reverse bearing, optional magnetic bearing, and planar distance.
Planar calculation
The tool uses atan2(ΔX, ΔY), normalized to 0°–360° clockwise from north. It does not calculate a great-circle route on Earth.
Declination comes from you
No location, date, or geomagnetic model is queried. When you explicitly enter east-positive declination, magnetic bearing = true bearing − declination.
GOOD TO KNOW
Common questions
Can I enter latitude and longitude?
No. Inputs are X/Y values in one flat coordinate system, not coordinates for a great-circle route.
Where does magnetic declination come from?
Obtain it from a trustworthy source for the relevant location and date, then enter it manually.
What coordinate units can I use?
Any consistent linear unit works; the distance result uses that same unit.
