Convert right angle to revolution
Please provide values below to convert right angle [None] to revolution [r], or Convert revolution to right angle.
1 None = 0.25 r. To convert right angle to revolution, multiply the value by 0.25; to go the other way, divide by it (1 r = 4 None). Both units measure angle and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 None = 0.25 r
- 1 r = 4 None
- 10 None = 2.5 r
- 100 None = 25 r
How to Convert Right Angle to Revolution
1 None = 0.25 r
Example: convert 15 None to r:
15 None = 15 × 0.25 r = 3.75 r

Right Angle
A right angle is an angle of exactly 90 degrees, representing a quarter turn.
History/Origin
The concept of the right angle has been used since ancient civilizations such as the Egyptians and Greeks, who formalized its measurement and significance in geometry and architecture.
Current Use
Right angles are fundamental in geometry, construction, engineering, and design, serving as a standard for perpendicularity and right-angled structures.
Revolution
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.
Frequently Asked Questions
What is 1 right angle in revolution?
1 right angle (None) = 0.25 revolution (r).
How do you convert right angle to revolution?
Multiply the right angle value by 0.25. For example, 25 None × 0.25 = 6.25 r.
What is 10 right angle in revolution?
10 None = 2.5 r.
Which unit is larger, the right angle or the revolution?
The revolution is the larger unit: 1 None equals only 0.25 r.
