About the units
- Degree
- A degree is 1/360 of a full turn, exactly π/180 radians, and is the everyday unit in geometry, navigation and maps.
- Revolution
- One revolution (full turn) is exactly 360 degrees, or 2π radians.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many revolutions are in one degree?
1 ° = 0.00277778 rev exactly.
How do I convert degrees to revolutions?
Use rev = ° × 0.002777777778. For example, 25 ° = 0.0694444 rev.
How many degrees are in one revolution?
1 rev = 360 °.
Why does my calculator give a strange answer for sine?
It is probably set to radians (RAD) while you are entering degrees. The sine of 30 degrees is 0.5, but the sine of 30 radians is about -0.988, so switch to DEG first.
What is the difference between MOA and MIL on a rifle scope?
MOA is an arcminute, 1/60 of a degree, while a MIL is a milliradian, about 3.438 MOA. At 100 meters a 0.1 MIL click moves impact 1 cm, and 1 MOA moves it about 2.9 cm.
