How This Tool Works

Gradians and degrees use different divisions of a full circle. A full circle is 400 grad or 360°, so 1 grad equals 0.9°.

To convert gradians to degrees, multiply the gradian value by 0.9. For example, 100 grad × 0.9 = 90°.

To convert degrees back to gradians, divide the degree value by 0.9.

Why This Matters in Measurement

Gradians are used in some surveying, mapping, and engineering contexts where a right angle is divided into 100 parts. Converting to degrees makes those angle measurements easier to compare with common geometry, navigation, and design references.

  • Surveying: Convert gon or gradian bearings into familiar degree measurements.
  • Engineering: Standardize angular inputs before using degree-based drawings or calculators.
  • Education: Check specialized angle notation against common right-angle and full-circle values.

Common Mistakes to Avoid

  • Use the correct full-circle ratio: 400 grad equals 360°, not 200 grad.
  • Remember the right angle check: 100 grad should equal 90°.
  • Do not confuse gradians with slope grade: This converter handles angular gradians, not percent grade.

Tips for Best Results

Use known checkpoints to sanity-check unusual inputs: 100 grad = 90°, 200 grad = 180°, and 400 grad = 360°.

If a result misses those values, confirm that the source value is an angular gradian measurement.
