arcsecond [arcsec] to gradian [grad] Converter
Quick Reference
1 arcsecond (arcsec) = 0.0003086419753 gradian (grad)
1 gradian (grad) = 3240 arcsecond (arcsec)
How to Convert arcsecond to gradian
1 arcsec = 0.0003086419753 grad
1 grad = 3240 arcsec
To convert arcsecond to gradian, divide the value by 3240 (equivalently, multiply by 0.0003086419753). To convert gradian back to arcsecond, multiply by 3240.
Example: convert 10 arcsec to grad:
10 arcsec = 10 x 0.0003086419753 = 0.003086419753 grad
arcsecond
Definition: An arcsecond (symbol: '') is a unit of angular measure equal to 1/60 of an arcminute or 1/3600 of a degree. It is used to express very small angles, particularly in astronomy and surveying.
History/origin: Like the arcminute, the arcsecond originates from the Babylonian sexagesimal system.
Current use: Arcseconds are used in astronomy for high-precision measurements of stellar positions, parallaxes, and proper motions. They are also used in surveying and geodesy for precise angle determination.
gradian
Definition: A gradian (also known as a gon or grade) is a unit of angular measure, defined as 1/400 of a full rotation. It is primarily used in surveying and some European countries.
History/origin: The gradian was introduced in France during the French Revolution as part of the metric system. It was intended to simplify calculations, as it is based on decimal divisions.
Current use: Gradians are mainly used in surveying, particularly in Europe. They are less common than degrees or radians in most other applications.
