Angles can be measured in degrees, arcminutes, arcseconds, radians, and gradians. While degrees are widely used, arcminutes are essential for astronomy, navigation, and surveying because they allow for more precise angle measurements.
What is an Arcminute?
An arcminute (′) is a subdivision of a degree:
- 1 degree = 60 arcminutes
- 1 full circle = 360° × 60 = 21,600′
Arcminutes are widely used in astronomy, surveying, navigation, and precision engineering to measure small angles.
What is a Degree?
A degree (°) is a standard unit of angle measurement:
- 1 full circle = 360°
- Degrees are commonly used in geometry, navigation, construction, and daily applications.
Arcminutes to Degrees Conversion Formula
To convert arcminutes into degrees, use the formula:
Formula:
degrees = arcminutes ÷ 60
Example Conversions
- Convert 60′ to degrees
- degrees = 60 ÷ 60 = 1°
- Convert 30′ to degrees
- degrees = 30 ÷ 60 = 0.5°
- Convert 120′ to degrees
- degrees = 120 ÷ 60 = 2°
- Convert 2700′ to degrees
- degrees = 2700 ÷ 60 = 45°
- Convert 21,600′ to degrees
- degrees = 21,600 ÷ 60 = 360°
