longitude wrap normalizer calculator online
Use longitude wrap normalizer online for unwrapped longitude deg. Input may span multiple rotations. Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.
How to use it
Enter unwrapped longitude deg. Select Calculate and check the labeled output. Copy or download the JSON result.
Options and example settings
Calculation method
normalized_longitude_deg = mod(unwrapped_longitude_deg+180,360)-180 (^ means exponentiation; trig functions ending in d use degrees).
Worked examples
Apply longitude wrap normalizer to the case below, keeping the displayed units and assumptions. Input may span multiple rotations.

}Choose the right tool
Choose great-circle tools for shortest spherical paths and rhumb tools for constant bearings. Spherical models differ from ellipsoidal survey calculations. Web-map tiles have latitude limits and grid bearings require a stated convergence convention.
Limitations and common mistakes
- Input may span multiple rotations. Spherical Earth radius 6371.0088 km unless another radius is displayed. Not an ellipsoidal survey or real-time navigation service.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
