Key Formulas
Degree → Radian
rad = ° × 0.0174533Radian → Degree
° = rad × 57.2958Degree → Gradian
grad = ° × 1.11111Gradian → Degree
° = grad × 0.9Formula
arcminutes = arcseconds ÷ 60Telescope pointing models, star trackers, and precision survey instruments output corrections in arcseconds for maximum resolution. But astronomical charts, navigation records, and field reports express positions in the more readable arcminute format. A telescope's polar alignment error of 180 arcseconds is better communicated as '3 arcminutes off Polaris' — immediately meaningful to another observer. This conversion simplifies arcsecond values for reporting and field communication.

Frequently Asked Questions
Real-World Examples
60 arcseconds — exactly 1 arcminute. The basic unit relationship: 1′ = 60″.
60 ″ = 1 ′
300 arcseconds (5 arcminutes) of telescope slew error — reported as '5 arcminutes off target' to the observatory coordinator.
300 ″ = 5 ′
240 arcseconds of polar alignment error — reported as '4 arcminutes' to decide if re-alignment is needed before a guided imaging session.
240 ″ = 4 ′
30 arcseconds — half an arcminute, the typical resolution of a precision theodolite, expressed in arcminutes for a survey report.
30 ″ = 0.5 ′
