How to Convert Minute of arc to Degree

Converting Minute of arc (MOA) to Degree (°) is a core calculation in Plane Angle, which measures the circular arc subtended between two intersecting rays or diverging lines. Because Degree is a broader physical scale than Minute of arc, converting from MOA to ° condenses the numerical figure. It takes 60 Minute of arc to equal a single Degree (1 MOA = 0.0166667 °). To convert any quantity, multiply by 0.0166667 (or divide by 60).

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (radian (rad)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 MOA = 0.0166667 radian (rad)
2. Target SI Bridge (ktarget):1 ° = 1 radian (rad)
Step-by-step substitution for Minute of arc → Degree:V(°) = V(MOA) × ( 0.0166667 / 1 ) = V(MOA) × 0.0166667
Mathematical FormulaValue in Degree = Value in Minute of arc × 0.016666667Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 75 MOA, applying the conversion factor yields exactly 1.25 °. At larger operational scale, 240 Minute of arc corresponds to 4 °.

Inverse check: 1 ° = 60 MOA.
