Exactly: 1 gradian = 0.015707963267948967 radians. The reverse factor is 1 radian = 63.66197723675813 gradians.

1 grad = 0.015708 rad; 10 grad = 0.15708 rad; 100 grad = 1.5708 rad. 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.
