1 gon = 0.9 °

Show the working
  1. 1 gon = 0.9 °
  2. 1 × 0.9 = 0.9 °

How to convert gradians to degrees

1 gon = 0.9 °, so multiply by 0.9 to go from gradians (gons) to degrees. Going the other way, 1 ° = 1.11111111111 gon.

° = gon × 0.9
gon = ° × 1.11111111111

Worked example:

1 gon = 0.9 °
5 × 0.9 = 4.5 °

About the units

Gradians (gon)
Gradians (gons), a specialised unit. Involves π, which no fraction equals exactly; this converter uses π to 50 significant digits, far beyond the 12 digits shown. Definition: NIST SP 811 Appendix B.8, factors for units listed alphabetically.
Degrees (°)
Degrees, a metric unit. Involves π, which no fraction equals exactly; this converter uses π to 50 significant digits, far beyond the 12 digits shown. Definition: BIPM SI Brochure, 9th edition (SI units, prefixes and units accepted for use with the SI).
