Frequently asked

What is the formula for converting Degree to Gradian?+
The formula is: 1 ° = 1.11111 gon. Type any value into the calculator above and the result appears instantly.
How do I convert Gradian back to Degree?+
Click the swap button (⇄) above to go to the Gradian → Degree converter, or use the inverse formula derived from the one shown.
When would I use radians instead of degrees?+
Radians are the natural unit for mathematics — sine, cosine, and most calculus formulas expect radians. Degrees are the everyday unit (you say "turn 90°", not "turn π/2 rad"). Gradians are mostly used in surveying and some European school systems.
