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 NATO milliradians
NATO milliradians (NATO mils) are a unit of angular measurement commonly used in military and artillery applications. They are derived from the radian, which is the standard unit for measuring angles in the International System of Units (SI). A radian is defined as the angle subtended at the center of a circle by an arc that is equal in length to the radius of the circle.
NATO mils are a more practical and convenient unit for military purposes, as they allow for easier estimation and calculation of angles in the field. One NATO mil is equal to 1/6400th of a circle, or approximately 0.05625 degrees. This means that a full circle is divided into 6400 NATO mils.
NATO mils are particularly useful in artillery and target acquisition, as they provide a simple and accurate way to measure angles and distances. They are often used to determine the direction and elevation of artillery fire, as well as to calculate the range to a target. NATO mils are also employed in land navigation and map reading, allowing military personnel to quickly and accurately determine their position and plan their movements. Overall, NATO mils provide a practical and efficient means of angular measurement in military operations.
