Frequently asked questions
What is the source unit in this conversion?
The source unit is the degree (deg). A degree is pi/180 radians.
What is the destination unit in this conversion?
The destination unit is the arcsecond (arcsec). One arcsecond is 1/3600 degree.
How do I convert degree to arcsecond?
Multiply the degree value by 3600. For example, 10 deg × 3600 = 36000 arcsec.
Is the degree to arcsecond conversion exact?
Yes. The relationship between these units is a fixed mathematical or SI-defined ratio, so the conversion factor is exact rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in degree needs to be compared with, or reported in, arcsecond, such as in engineering, scientific, or everyday calculations.
Can I convert arcsecond back to degree?
Yes. Multiply the arcsecond value by 0.000278 to get degree.

About this conversion
This page converts degree (deg) to arcsecond (arcsec) within the angle converter.
A degree is pi/180 radians. One arcsecond is 1/3600 degree.
The formula is arcsecond = degree × 3600, based on each unit's fixed relationship to the angle converter's base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
