Definition of Radian
- Definition
The radian (rad) is the SI derived unit of plane angle. It is defined as the angle subtended at the center of a circle by an arc equal in length to the radius.
Although mathematically dimensionless, the radian is retained as a named unit in the SI to preserve clarity in scientific, engineering, physics, trigonometry, and calculus contexts.
- Exact factor
- Base unit: 1 rad = 1 rad; full circle: 2π rad = 360°
- Examples
- π rad = 180°
- 1 rad ≈ 57.2958°
- 2π rad = 1 turn
Definition of Minute
- Definition
An arcminute (minute of arc) is 1/60 of a degree.
It is used in astronomy, optics, navigation, geodesy, and surveying for small angular measurements.
- Exact factor
- 1′ = 1/60° = π/10,800 rad (exact)
- Examples
- 60′ = 1°
- 30′ = 0.5°
About the Radian
Facts & Uses
- SI coherent unit of plane angle: 1 rad = the angle subtended at a circle's center by an arc equal in length to the radius. 1 full circle = 2π rad ≈ 6.283 rad.
- Universal in mathematics, physics, engineering, and computer graphics — wherever calculus or trigonometric derivatives are involved.
- Standard for angular velocity (rad/s), angular acceleration (rad/s²), and phase angles in electrical engineering and signal processing.
- Common reference: π/6 rad = 30°, π/4 = 45°, π/3 = 60°, π/2 = 90°, π = 180°, 2π = 360°.
Curiosities
- The radian was first proposed by Roger Cotes in 1714, but the name "radian" wasn't coined until 1873 by James Thomson (brother of Lord Kelvin).
- Programming functions like Math.sin() and Math.cos() in JavaScript, Python, C, and most languages take radians as input — a frequent source of bugs for developers expecting degrees.
- The reason calculus prefers radians: the derivative of sin(x) is cos(x) only when x is in radians. With degrees, you'd need a π/180 factor everywhere.
- Approximate equivalents: 1 rad ≈ 57.2958° ≈ 63.66 grad ≈ 3437.75 arcminutes.

About the Minute
Facts & Uses
- 1 arcminute (′) = 1/60 of a degree = π/10800 rad ≈ 0.000291 rad. NOT to be confused with the time minute.
- Standard for geographic latitude/longitude (1 nautical mile = 1 arcminute of latitude, the original definition).
- Used in astronomy for angular sizes of celestial objects (the full Moon ≈ 31′, Jupiter ≈ 30-50″ depending on opposition).
- Common in marksmanship as MOA (Minutes of Angle) for scope adjustment: 1 MOA ≈ 1 inch at 100 yards (actually 1.047″).
Curiosities
- The arcminute symbol ′ (prime, U+2032) is distinct from the apostrophe ('); using the wrong character is a common typesetting error in scientific writing.
- Human visual acuity: a person with 20/20 vision can distinguish two points separated by about 1 arcminute — the basis of the Snellen eye chart design.
- Geographic coordinates: 40°45′ N reads as "forty degrees, forty-five minutes north" — a precision of about 1.85 km in latitude.
- Approximate equivalents: 1 arcminute = 1/60° = 60 arcseconds ≈ 0.000291 rad.
