Second Of Arc To Sign (″ to sign) Converter

Welcome to the Second of Arc to Sign (″ to sign) Converter! This tool is designed to help you easily convert measurements expressed in seconds of arc into the corresponding value in signs. While not a commonly encountered conversion in everyday life, understanding these units and how they relate can be useful in specific fields, particularly those dealing with angular measurements in astronomy or historical contexts.

Let’s break down what these units represent. A second of arc, denoted by the symbol ″, is a unit of angular measurement. It is defined as 1/3600th of a degree. To put that into perspective, a degree is 1/360th of a full circle. So, a second of arc is an incredibly small angle, representing 1/1,296,000th of a full circle. Signs, on the other hand, are a historical unit of angular measurement, primarily used in astronomy and astrology. A sign represents 30 degrees, which is 1/12th of a full circle. The twelve signs of the zodiac are a familiar example of this division of the ecliptic into 30-degree segments.

Converting from seconds of arc to signs involves a straightforward calculation based on the definitions of these units. Since one sign is equal to 30 degrees, and one degree is equal to 3600 seconds of arc, we can determine the number of seconds of arc in one sign. One sign = 30 degrees * 3600 ″/degree = 108,000 ″. Therefore, to convert a value in seconds of arc to signs, you simply divide the number of seconds of arc by 108,000. Our converter performs this calculation for you, providing a quick and accurate conversion between these two angular units.
