About seconds
A degree is divided into 60 minutes, and each minute is further divided into 60 seconds. This means that there are 3,600 seconds in a degree. Seconds of degrees are typically used when a higher level of precision is required, such as in navigation or astronomy. For example, when determining the position of a celestial object, astronomers may need to measure the angle in seconds of degrees to accurately track its movement.
About Centiradians
Centiradians, also known as centesimal radians or centrad, are a unit of angular measurement commonly used in trigonometry and geometry. The centiradian is derived from the radian, which is the standard unit for measuring angles in the International System of Units (SI). While a radian is defined as the angle subtended at the center of a circle by an arc equal in length to the radius of the circle, a centiradian is one-hundredth of a radian.
The use of centiradians can be particularly useful when working with small angles or when precise measurements are required. Since there are 100 centiradians in a radian, it allows for finer divisions and more accurate calculations. For example, when measuring the angles of very small objects or when dealing with intricate geometric shapes, using centiradians can provide a more precise representation of the angles involved. Additionally, centiradians are often used in scientific and engineering fields where precise measurements are crucial, such as in optics, astronomy, and surveying.
