The second of arc, abbreviated as arcsec, is a unit of angular measurement that represents one-sixtieth of an arcminute or one three-thousand six-hundredth of a degree. This precise measurement is crucial in fields such as astronomy, navigation, and various engineering disciplines, where accurate angular measurements are essential.
The second of arc is part of the sexagesimal system, which divides a circle into 360 degrees, each degree into 60 arcminutes, and each arcminute into 60 arcseconds. This standardization allows for consistent measurements across various scientific and engineering applications.
The concept of measuring angles dates back to ancient civilizations, with the Babylonians being among the first to use a base-60 system. The second of arc has evolved over centuries, becoming a vital unit in modern astronomy and navigation, particularly with the advent of telescopes and precise navigational instruments.
To convert degrees to seconds of arc, simply multiply the degree measurement by 3600 (since there are 3600 seconds in a degree). For example, if you have an angle of 1 degree: 1 degree × 3600 = 3600 arcseconds.
The second of arc is widely used in various applications, including:

The millidegree (m°) is a unit of angular measurement that represents one-thousandth of a degree. It is commonly used in various scientific and engineering applications where precise angle measurements are crucial. This unit allows for finer granularity in angle measurement, making it particularly useful in fields such as optics, navigation, and robotics.
The millidegree is part of the International System of Units (SI) and is derived from the degree, which is a standard unit for measuring angles. One degree is equal to 1,000 millidegrees, ensuring a straightforward conversion and standardization across various applications.
The concept of measuring angles dates back to ancient civilizations, where degrees were used to divide circles. The millidegree emerged in the 20th century as precision in engineering and science became increasingly important. As technology advanced, the need for finer measurements led to the adoption of the millidegree in various technical fields.
To convert degrees to millidegrees, simply multiply the degree value by 1,000. For example, if you have an angle of 2 degrees, the calculation would be: [ 2 \text{ degrees} \times 1,000 = 2,000 \text{ millidegrees} ]
Millidegrees are particularly useful in applications requiring high precision, such as:
Using the millidegree conversion tool is straightforward:
1. How do I convert degrees to millidegrees?
