About Converting Arcseconds to Arcminutes
Arcsecond and Arcminute are the two standard ways to measure angles — degrees for everyday and navigational use, radians for calculus and physics — so converting between them comes up constantly in math, engineering, and programming. Specifically: One arcsecond is 1/3600 degree, and one arcminute is 1/60 degree.
Formula
arcminutes = arcseconds × 0.0166666666667
This factor comes from each unit's defined relationship to the category's base unit: 1 arcsecond equals 0.0000048481368111 base units, and 1 arcminute equals 0.000290888208666 base units, so dividing one by the other gives the direct arcsecond-to-arcminute factor of 0.0166666666667.
Simple example
1 arcsec × 0.01666666667 = 0.0166666667 arcmin
1 arcsecond = 0.0166666667 arcminutes.
Real-world example
90 arcsec × 0.01666666667 = 1.5 arcmin
90 arcseconds = 1.5 arcminutes.
