Convert circle to revolution
Enter a value below to convert circle [None] to revolution [r]. Reverse conversion: Convert revolution to circle.
1 None = 1 r. To convert circle to revolution, multiply the value by 1; to go the other way, divide by it (1 r = 1 None). Both units measure angle and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Circle to Revolution: Quick Reference
- 1 None = 1 r
- 1 r = 1 None
- 10 None = 10 r
- 100 None = 100 r
How to Convert Circle to Revolution
1 None = 1 r
Example: convert 15 None to r:
15 None = 15 × 1 r = 15 r

Circle: Definition and Use
A circle is a geometric shape consisting of all points in a plane that are equidistant from a fixed center point.
History/Origin
The concept of the circle dates back to ancient civilizations such as the Egyptians and Greeks, who studied its properties and used it in astronomy, architecture, and mathematics. The Greek mathematician Euclid formalized many properties of the circle in his works.
Current Use
In the context of angle measurement, a circle is used as the basis for defining degrees, with 360 degrees representing a full rotation. It is fundamental in fields like geometry, engineering, and navigation for measuring angles and designing circular objects.
Revolution: Definition and Use
A revolution is a complete turn or rotation around a central point, typically measuring 360 degrees in angular terms.
History/Origin
The concept of a revolution as a full rotation has origins in ancient geometry and astronomy, with the term 'revolution' historically used to describe celestial orbits and rotations in various cultures.
Current Use
In modern contexts, the unit 'revolution' (symbol: r) is used to quantify angular displacement, especially in mechanical and engineering applications, where one revolution equals 360 degrees or 2π radians.
Circle to Revolution: Frequently Asked Questions
What is 1 circle in revolution?
1 circle (None) = 1 revolution (r).
How do you convert circle to revolution?
Multiply the circle value by 1. For example, 25 None × 1 = 25 r.
What is 10 circle in revolution?
10 None = 10 r.
Which unit is larger, the circle or the revolution?
The revolution is the larger unit: 1 None equals only 1 r.
