′ to rad

minute

• Definition: A minute is a unit of angular measurement equal to one-sixtieth of a degree. It is commonly used to describe small angles.

• Symbol: The symbol for minute is ‘′’ (a prime symbol).

• Usage: Minutes are often used in navigation, astronomy, and various fields of engineering where precision is required in measuring angles.

radian

• Definition: A radian is a unit of angular measure that describes the angle subtended at the center of a circle by an arc equal in length to the radius of the circle.

• Symbol: The symbol for radian is ‘rad’.

• Usage: Radians are widely used in mathematics, physics, and engineering, particularly in calculations involving circular motion and oscillations.

Origin of the minute

• The term “minute” comes from the Latin phrase “pars minuta prima,” meaning “first small part.” This reflects its function as a subdivision of a degree, which itself is derived from the ancient measurement systems.

Origin of the radian

• The concept of the radian was introduced in the late 18th century by mathematicians such as Roger Cotes and is based on the geometric relationship between the radius and the arc of a circle. The name “radian” derives from the word “radius.”
