Convert arcminutes to degrees by entering an angle in arcmin, or convert between arcminutes, arcseconds, degrees, radians, turns and gradians.
Common Mistakes Quick tips
- Choose the desired output in Solve for and enter the known angle in its own unit; the answer appears below Calculate.
- Confusing angle arcminutes (โฒ) with minutes of time; they are not the same unit.
- Mixing decimal degrees with DMS (degreesโminutesโseconds) without converting properly.
- Check both the known-angle unit and Solve for output unit; changing an input unit converts its current value.
When to Use This Calculator
- Converting telescope or camera field of view/resolution from arcminutes/arcseconds to degrees.
- GIS, mapping, and navigation tasks involving degreesโminutesโseconds (DMS) and decimal degrees.
- Ballistics and optics work where MOA (minute of arc) adjustments are related to degrees.
Input Definitions
- Arc Minutes/Arc Seconds โ 1ยฐ = 60โฒ; 1โฒ = 60โณ; therefore 1ยฐ = 3600โณ.
- Solve for โ choose degrees, arcminutes, arcseconds, radians, turns, or gradians as the output.
- Conversions โ deg = arcmin รท 60; arcmin = deg ร 60; rad = deg ร ฯ/180; turn = deg รท 360; grad = deg รท 0.9.

Arc Minute to Degrees Formula
The following formulas convert arc minutes (and arcseconds) to degrees and back.
deg = (arcmin) / (60) arcmin = 60 deg
- 1 degree (ยฐ) = 60 arcminutes (โฒ) = 3600 arcseconds (โณ).
- 1 radian = 180/ฯ degrees โ 57.29578ยฐ; 1 turn = 360ยฐ; 1 grad = 0.9ยฐ.
How do you convert arc minutes to degrees? Divide arc minutes by 60 to get degrees; for arcseconds, divide by 3600.
How do you convert degrees to arc minutes? Multiply degrees by 60 to get arc minutes; multiply degrees by 3600 to get arcseconds.

Example Problem
Convert 135 arcminutes to degrees.
Use the formula: deg = arcmin รท 60.
deg = 135 รท 60 = 2.25ยฐ
