Arcsec also known as arc second or second arc is a unit of angular measurement. One second of arc is equal to 1/60 of an arcminute, 1/3600 of a degree, 1/296000 of a turn. That means one full circle will have 1296000 arcseconds. Similar to arcmin, arcsec was originated in Babylonian astronomy as sexagesimal subdivisions of the degree. It is primarily used in fields where most of the work involves working with small angles such as optometry, ophthalmology, and astronomy. In astronomy related work, it is used for comparison of angular diameter of Moon, Sun, and planets. Apart from that, it is also used in cartography and navigation. The symbol for Arcsecond is arcsec.
Use this Arcsecond converter to change values into other angle units. Enter a value, choose the target unit, and review the converted result without applying the conversion factor by hand.
It is useful when a measurement is recorded in Arcsecond but a formula, specification, or comparison requires another angle unit. The available target units are listed below the example and conversion table.
Arcsecond is one of the units available in this angle category. Use the result as a reference, and retain suitable precision when the value will be used in a technical or scientific calculation.
The calculator formats results for readability. Display rounding can affect the last digits, so check the original input and the shown precision before copying a result into a report or further formula.

When comparing Arcsecond with another unit, make sure both values describe the same type of measurement. The converter applies the available unit relationship and presents the result in the target unit you select.
How to Use Arcsecond Converter
- Select Arcsecond from the first dropdown and enter the amount you want to convert.
- Choose the target unit from the second dropdown, such as Cycle.
- The converter instantly calculates the value and displays the converted result.
- Use the result for comparison, calculations, or quick reference when working with angle measurements.
For repeated conversions, keep the source unit as Arcsecond and change only the target unit. If the result will be used in another calculation, use the displayed precision as a guide and verify the final rounding required by your context.
