Radian to Mil Converter
Angle · unit-converter
Convert Radian to Mil with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through radians with fixed definitions (360° per turn, 400 grad per turn, 60′ per degree, 60″ per minute, plus practical units like MOA, urad, and NATO 6400 mils per turn).
About Radian
The radian is the SI unit of plane angle. One radian is the angle subtended by an arc equal to the radius; 2π rad = one full circle.
About Mil
NATO mils split a full circle into 6,400 parts for artillery and tactical optics; 1 mil = 2π/6400 rad.
How to convert radians to mils (nato, 6400)
1 radian equals 1018.5916357881301 mil in this tool (via radian):
1 rad = (1 rad ÷ 0.0009817477042468104 rad) mil = 1018.5916357881301 mil
Each radian carries 1 rad and each mil 0.0009817477042468104 rad, so one rad equals 1 ÷ 0.0009817477042468104 mil.
Let θ(rad) be the angle in Radian (rad), and θ(mil) in Mil (mil). Then:
θ(mil) = θ(rad) × (1 / 0.0009817477042468104)
Equivalently, divide by how many rad fit into one mil (rad per mil divided by rad per rad):
θ(mil) = θ(rad) ÷ 0.0009817477042468104
Examples
Example #1: Convert 1 rad to mil
1 rad = 1 rad × (1/0.0009817477042468104) mil = 1018.59163579 mil
1 rad = 1 rad ÷ 0.0009817477042468104 = 1018.59163579 mil
1 rad × (1/0.0009817477042468104) = 1,018.591636 mil
Example #2: Convert 10 rad to mil
10 rad = 10 rad × (1/0.0009817477042468104) mil = 10185.9163579 mil
10 rad = 10 rad ÷ 0.0009817477042468104 = 10185.9163579 mil
10 rad × (1/0.0009817477042468104) = 10,185.916358 mil
Summary
To convert Radian to Mil, multiply the value in rad by (1 rad per rad) / (0.0009817477042468104 rad per mil). Equivalently: value_mil = value_rad × (1 / 0.0009817477042468104). Numerically, 1 rad equals 1018.5916357881301 mil.
Relationship context
Both Radian and Mil are converted by fixed multiples of the radian. Multiplying by (rad per rad) ÷ (rad per mil) matches passing through radians, keeping degrees, gradians, arc minutes, NATO mils, and revolutions consistent on the hub.
