Convert Radians to Gradians

The rad-to-grad conversion appears often when working with angle data across different unit systems. Angle conversions connect degrees (everyday use), radians (mathematics and physics), and gradians (used in some surveying applications).

Formula: Multiply the radians value by 63.662. In equation form: grad = rad × 63.662.

One radians equals approximately 63.662 grad. This means you can multiply any rad value by 63.662 to get the equivalent in grad.

For instance, converting 100 rad gives 6366.2 grad. Try different values using the quick-value chips or type directly into the input field.

Common mistake: When converting to radians for trigonometry, make sure your calculator is in the correct angle mode (degrees vs. radians).
