Arc Minute to Radian Converter

Angle · unit-converter

Convert Arc Minute to Radian 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 Arc Minute

An arc minute is 1/60 of a degree (π/10,800 rad). Used in astronomy, navigation, and precision optics (MOA).

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.

How to convert arc minutes to radians

1 arc minute equals 0.0002908882086657216 radian in this tool (via radian):

1 arcmin = (0.0002908882086657216 rad ÷ 1 rad) rad = 0.0002908882086657216 rad

Each arc minute carries 0.0002908882086657216 rad and each radian 1 rad, so one arcmin equals 0.0002908882086657216 ÷ 1 rad.

Let θ(arcmin) be the angle in Arc Minute (arcmin), and θ(rad) in Radian (rad). Then:

θ(rad) = θ(arcmin) × (0.0002908882086657216 / 1)

Equivalently, divide by how many arcmin fit into one rad (rad per rad divided by rad per arcmin):

θ(rad) = θ(arcmin) ÷ 3437.7467707849396

Examples

Example #1: Convert 1 arcmin to radian

1 arcmin = 1 arcmin × (0.0002908882086657216/1) rad = 0.0002908882 rad

1 arcmin = 1 arcmin ÷ 3437.7467707849396 = 0.0002908882 rad

1 arcmin × (0.0002908882086657216/1) = 0.000291 rad

Example #2: Convert 10 arcmin to radian

10 arcmin = 10 arcmin × (0.0002908882086657216/1) rad = 0.0029088821 rad

10 arcmin = 10 arcmin ÷ 3437.7467707849396 = 0.0029088821 rad

10 arcmin × (0.0002908882086657216/1) = 0.002909 rad

Summary

To convert Arc Minute to Radian, multiply the value in arcmin by (0.0002908882086657216 rad per arcmin) / (1 rad per rad). Equivalently: value_rad = value_arcmin × (0.0002908882086657216 / 1). Numerically, 1 arcmin equals 0.0002908882086657216 rad.

Relationship context

Both Arc Minute and Radian are converted by fixed multiples of the radian. Multiplying by (rad per arcmin) ÷ (rad per rad) matches passing through radians, keeping degrees, gradians, arc minutes, NATO mils, and revolutions consistent on the hub.
