Convert revolution to right angle
Please provide values below to convert revolution [r] to right angle [None], or Convert right angle to revolution.
1 r = 4 None. To convert revolution to right angle, multiply the value by 4; to go the other way, divide by it (1 None = 0.25 r). Both units measure angle and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 r = 4 None
- 1 None = 0.25 r
- 10 r = 40 None
- 100 r = 400 None
How to Convert Revolution to Right Angle
1 r = 4 None
Example: convert 15 r to None:
15 r = 15 × 4 None = 60 None

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.
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.
Frequently Asked Questions
What is 1 revolution in right angle?
1 revolution (r) = 4 right angle (None).
How do you convert revolution to right angle?
Multiply the revolution value by 4. For example, 25 r × 4 = 100 None.
What is 10 revolution in right angle?
10 r = 40 None.
Which unit is larger, the revolution or the right angle?
The revolution is the larger unit: 1 r = 4 None.
