Exactly: 1 gradian = 0.0025 turns. The reverse factor is 1 turn = 399.99999999999994 gradians.
1 grad = 0.0025 turn; 10 grad = 0.025 turn; 100 grad = 0.25 turn. Use the full conversion table below for more reference values.
The gradian was defined during the French metrication effort so a right angle equals exactly 100 gradians, making a full turn 400 — nicer for decimal math, less aligned with astronomy and timekeeping (360 divides evenly by 2, 3, 4, 5, 6, 8, 9, 10, 12…). Engineering in most countries still uses degrees; gradians survive mainly in surveying and some European calculators.
