About these units

rad
Radians, common in math and programming.
grad
Gradians, used in some surveying contexts.

Before you use the result

rad to grad 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 rad converts to 63.6619772 grad. Use this known value to sanity-check a spreadsheet, homework solution, spec sheet, or manual calculation.

How to use the Radians to Gradians Converter

Convert radians (rad) to gradians (grad) with the exact angle formula, worked examples, and a common-values table. Use the instant result for the radians to gradians conversion, then check the common-value table, reverse link, and unit notes before copying the answer.

  1. 1

    Enter Radians

    Type the radians value you want to convert. Decimal values work when you need a partial unit.

  2. 2

    Read Gradians

    Use the main result for the exact gradians value, then scan the common-value table for nearby reference points.

  3. 3

    Confirm Radians to Gradians

    Confirm the radians to gradians unit symbols before using the number in a report, product listing, invoice, or assignment.
