## How to Convert Radians to Degrees Using an Easy Conversion Formula

Convert radians to degrees with this simple formula:

Converting a radian angle measurement to a degree measurement involves multiplying your angle by the conversion ratio to find the result. A radian is equal to 57.29578 degrees, so to convert simply multiply by 57.29578.

**For example:**

Radians and degrees are both units used to measure angle.

A radian is an angle measurement and can be abbreviated as * rad*, for example 1 rad.
A degree is an angle measurement and can be abbreviated as *°*, for example 1°.

Degrees can also be expressed using minutes and seconds as an alternative to using the decimal form. Minutes and seconds are expressed using the prime (′) and double-prime (″) characters, although a single-quote (') and double-quote (") are often used for convenience.

One minute is equal to 1/60th of a degree and one second is equal to 1/60th of a minute.

There are 360 degrees in a revolution, or circle. 360 has 24 divisors, and is easily divided by 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120 and 180. This makes it a fairly easy number to work with. There are also 360 days in the Persian calendar year, and many theorize that early astronomers used 1 degree per day.

Protractors are commonly used to measure angles in degrees. They are semi-circle or full-circle devices with degree markings allowing a user to measure an angle in degrees. Learn more about how to use a protractor or download a printable protractor.

A radian is the measurement of the angle from the start to the end of an arc equal to the radius of the circle. 1 radian is equal to 180/π, or about 57.29578°. There are about 6.28318 radians in a circle. The radian is the standard SI unit of measurement for an angle.
