Convert arcsecond to arcminute

Arcsecond

An arcsecond is an angle unit equal to one sixtieth of an arcminute.

Arcseconds developed from sexagesimal angle subdivision and remain important in precise angular measurement.

Arcseconds are used in astronomy, optics, surveying, geodesy, angular resolution, telescope pointing, and precision alignment.

Arcminute

An arcminute is an angle unit equal to one sixtieth of a degree or 60 arcseconds.

Arcminutes developed from sexagesimal angle subdivision and remain common in astronomy, navigation, and mapping.

Arcminutes are used in astronomy, optics, mapping, navigation, surveying, angular resolution, and precision alignment.

How to Convert Arcsecond to Arcminute

Mathematically, arcminute (′) = arcsecond (″) converted with the formula below.

1 ″ = 0.016667 ′

1 ′ = 60 ″

Formula: value × 0.0166666666667

Example: 15 ″ = 0.25 ′

1. Start with the angle value in arcseconds.
2. Use the exact relationship that 60 arcseconds equals 1 arcminute.
3. Divide the arcsecond value by 60.
4. Report the converted result in arcminutes.

Precision note: Use arcminutes = arcseconds / 60. Keep precision aligned with the measurement tolerance or coordinate accuracy.

How many ″ in ′ and ′ in ″

1 ″ = 0.016667 ′

1 ′ = 60 ″

Common Use Cases for ″ to ′

• Summarizing telescope, optics, or astronomy values from arcseconds to arcminutes.
• Converting precision survey or geodesy values into a slightly broader angle unit.
• Checking angular-resolution data that mixes arcseconds and arcminutes.
• Preparing readable angle tables from very fine source measurements.
