About Gradians
Gradians, also known as gons or grads, divide a circle into 400 equal parts. This means that a right angle is equal to 100 gradians, a full circle is 400 gradians, and so on. Gradians were introduced as an alternative to degrees and radians, aiming to provide a more convenient and decimal-based system for measuring angles.
While gradians are not as commonly used as degrees or radians, they do have their applications. For example, they are often used in surveying and navigation, where angles need to be measured and calculated with high precision. Additionally, gradians can be easily converted to degrees or radians, making them a versatile unit of measurement.
While radians are the standard unit for measuring angles in mathematics and physics, gradians offer an alternative system that can be useful in specific fields. Whether it's for precise measurements in surveying or for converting between different angle units, gradians provide a decimal-based approach to quantifying angles.
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.
