How to Convert Degree to Minute of arc

Converting Degree (°) to Minute of arc (MOA) is a core calculation in Plane Angle, which measures the circular arc subtended between two intersecting rays or diverging lines. Because Degree represents a larger magnitude than Minute of arc, converting from ° to MOA expands the numerical figure. Exactly 1 Degree encompasses 60 Minute of arc. To convert any quantity, multiply the value in Degree 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 ° = 1 radian (rad)
2. Target SI Bridge (ktarget):1 MOA = 0.0166667 radian (rad)
Step-by-step substitution for Degree → Minute of arc:V(MOA) = V(°) × ( 1 / 0.0166667 ) = V(°) × 60
Mathematical FormulaValue in Minute of arc = Value in Degree × 60Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 15 °, applying the conversion factor yields exactly 900 MOA. At larger operational scale, 2500 Degree corresponds to 150000 MOA.

Inverse check: 1 MOA = 0.0166667 °.

Frequently Asked Questions

There are exactly 60 minute of arcs (MOA) in 1 degree (°). To calculate larger amounts manually, simply multiply your total number of degrees by the conversion multiplier of 60.

The mathematical formula to convert degrees to minute of arcs is: [value] * 60 = minute of arcs. Rather than doing the math manually, you can use our high-precision online calculator to process this exact equation instantly without rounding errors.

To perform the reverse calculation from minute of arcs back to degrees, you must divide your starting value by 60. Our bidirectional tool automatically computes this inverse equation the moment you type into the minute of arc input field.

1 Degree is larger than 1 Minute of arc. Specifically, 1 Degree equals exactly 60 minute of arcs, making it 60 times larger (a difference of 1.78 orders of magnitude). Therefore, quantities expressed in minute of arcs require a larger numerical value to represent the same physical amount.

A typical perpendicular orthogonal intersection right angle (90°) measures 90 °, which corresponds to 5400 Minute Of Arc (Minute of arc).
