About Converting Arcminutes to Arcseconds
Arcminute and Arcsecond 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 arcminute is 1/60 degree, and one arcsecond is 1/3600 degree.
Formula
arcseconds = arcminutes × 60
This factor comes from each unit's defined relationship to the category's base unit: 1 arcminute equals 0.000290888208666 base units, and 1 arcsecond equals 0.0000048481368111 base units, so dividing one by the other gives the direct arcminute-to-arcsecond factor of 60.
Simple example
1 arcmin × 60 = 60 arcsec
1 arcminute = 60 arcseconds.
Real-world example
90 arcmin × 60 = 5,400 arcsec
90 arcminutes = 5,400 arcseconds.
