About these units
- grad
- Gradians, used in some surveying contexts.
- rad
- Radians, common in math and programming.
Before you use the result
grad to rad context and checks
- Best use
- Use angle conversions for geometry, surveying, machining, slope, and navigation notes where the source is a rotation or bearing.
- Common mistake
- Do not mix angular units with percent grade unless the page explicitly handles the tangent relationship.
- Precision note
- Keep extra digits until the final result because small angle differences can matter in layout, optics, and slope work.
Example check: 1 grad converts to 0.0157079633 rad. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.
