1 Milliradian = 0.0637 Gradian
Key Formulas
Degree → Radian
rad = ° × 0.0174533Radian → Degree
° = rad × 57.2958Degree → Gradian
grad = ° × 1.11111Gradian → Degree
° = grad × 0.9Formula
gradians = mrad × 0.06366198Military fire-control systems and tactical optics use milliradians globally. European and Middle Eastern civil surveying databases and software work in gradians. When a military engineering unit sets up a forward observation post and must integrate their mrad-based targeting system with a gradian-referenced local survey grid, converting mrad readings to grad values is the entry step for coordinate reconciliation. The factor 0.0637 comes from 1 mrad = 0.001 rad × (200 grad / π).

1,570.8 mrad — exactly 100 grad (90°, a right angle). Confirms the conversion scales correctly at the right-angle reference point.
1570.8 mrad = 100 grad
1 mrad — 0.0637 grad. The conversion factor for single-mrad corrections entered into gradian-mode survey software.
1 mrad = 0.0637 grad
15.708 mrad — exactly 1 grad (= 0.9°). Used to verify that 1 gradian steps in the survey database correspond to the correct mrad value in the targeting system.
15.708 mrad = 1 grad
100 mrad — 6.37 grad, a fire direction correction angle entered into a gradian-referenced artillery coordination grid.
