Radians to Gradians Converter

Summary

Convert any angle from radians to gradians (grad/gon) using the formula gradians = radians × 200/π, with a step-by-step breakdown and common angle reference table.

How it works

1. Enter an angle in radians in the input field.
2. The converter applies the formula: gradians = radians × (200 / π).
3. The result is displayed in gradians (grad/gon) rounded to 6 decimal places.
4. The step-by-step panel shows the substituted formula so you can verify the math.
5. Click any row in the reference table to load that angle into the converter.

Use cases

• Converting radian angles to gradians for surveying and geodesy calculations.
• Checking gradian values when working with civil engineering or land measurement tools.
• Verifying manual radian-to-gradian conversions for coursework or exams.
• Preparing angles for GIS software that accepts gradian input.
• Teaching or learning the relationship between radians, degrees, and gradians.
• Quick lookup of common angles like π/2 rad = 100 grad or π rad = 200 grad.
