Gradians to Revolutions formula and what each symbol means
rev = grad × 0.0025
| Symbol | Meaning |
|---|---|
| grad | Gradian |
| rev | Turn |
Gradians to Revolutions examples
1 grad
1 grad × 0.0025 = 0.0025 rev.

10 grad × 0.0025 = 0.025 rev.
100 grad
100 grad × 0.0025 = 0.25 rev.
Gradians compared with Revolutions
One rev is 400 times as large as one grad, so your number gets smaller when you convert gradians to revolutions and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About gradians and revolutions
Gradian (grad): 1/400 of a full turn, also called a gon. Turn (rev): One full turn, 360 degrees or 2π radians.
Where gradians to revolutions conversions are used
Machining and construction use degrees; some drafting and military work uses gradians or mils. Trigonometry functions in most programming languages expect radians.
How to calculate Gradians to Revolutions step by step
- Enter the value in grad (the starting unit).
- Multiply by 0.0025, because 1 grad = 0.0025 rev.
- The product is the value in rev. To go back, divide by 0.0025 or multiply by 400.
