§02The Formula

How it’s calculated

1 radian = 63.662 gradians → value_in_gradian = value_in_radian × 63.662

Where

value_in_radian
The number of radians you start with (the value you enter above)
value_in_gradian
The equivalent number of gradians (the result)
factor
The exact conversion ratio — 63.662 — anchored to SI definitions, not rounded
§03Practical Example

Step-by-step walkthrough

Scenario

Convert 5 radians to gradians.

  1. 01Look up the SI factors: 1 radian = 1 base units, 1 gradian = 0.015707963267948967 base units.
  2. 02Divide to get the conversion ratio: 1 / 0.015707963267948967 = 63.662.
  3. 03Multiply by the quantity: 5 × 63.662 = 318.31.
  4. 04So 5 radians = 318.31 gradians.
