Degrees and radians are 2 units for measuring angles.[one] A circle contains 360 degrees, which is the equivalent of 2π radians, so 360° and 2π radians represent the numerical values for going "one time around" a circle.[2] Sound disruptive? Don't worry, yous can easily convert degrees to radians, or from radians to degrees, in just a few easy steps.

Write down the number of degrees you want to convert to radians. [3] Let's work with a few examples so y'all really go the concept down. Here are the examples you'll be working with:
- Example ane: 120°
- Example 2: 30°
- Case iii: 225°
-
two
Multiply the number of degrees past π/180. To sympathise why you lot have to do this, you lot should know that 180 degrees constitute π radians. Therefore, 1 degree is equivalent to (π/180) radians. Since you know this, all you lot have to exercise is multiply the number of degrees you're working with by π/180 to convert it to radian terms. You can remove the degree sign since your respond will exist in radians anyway. Here'due south how to set it up:[4]
- Example 1: 120 10 π/180
- Example 2: 30 ten π/180
- Instance iii: 225 x π/180

Exercise the math. Simply carry out the multiplication process, by multiplying the number of degrees by π/180. Recall of it like multiplying 2 fractions: the start fraction has the number of degrees in the numerator and "i" in the denominator, and the second fraction has π in the numerator and 180 in the denominator. Here's how you do the math:
- Example 1: 120 x π/180 = 120π/180
- Example 2: 30 10 π/180 = 30π/180
- Example 3: 225 ten π/180 = 225π/180

Simplify. Now, you've got to put each fraction in lowest terms to get your final answer. Discover the largest number that tin evenly divide into the numerator and denominator of each fraction and use information technology to simplify each fraction. The largest number for the kickoff example is 60; for the second, it'due south 30, and for the third, it's 45. But you don't have to know that correct away; yous tin can just experiment past commencement trying to carve up the numerator and denominator past 5, 2, 3, or whatever works. Hither's how you practise it:
- Example ane: 120 x π/180 = 120π/180 ÷ 60/lx = two/3π radians
- Case 2: 30 x π/180 = 30π/180 ÷ 30/30 = one/6π radians
- Instance iii: 225 10 π/180 = 225π/180 ÷ 45/45 = v/4π radians

Write down your answer. To be clear, y'all can write down what your original angle measure out became when converted to radians. And then, you're all done! Hither'south what you do:
- Case one: 120° = 2/3π radians
- Example ii: 30° = 1/6π radians
- Case 3: 225° = five/4π radians

Question
How do I derive the formula for the conversion of degrees to radians?
Anan Shah
Community Answer
Simply: π=180 or π=180*1 degree and therefore, 1degree= π/180, thus, caste measure= radian measure * π/180.

Question
What is 63 degree fourteen min 51 sec in radian course?
First convert the angle to a decimal. There are 60 seconds in a minute, 60 minutes in a degree, and 3600 seconds (60 x sixty) in a degree. 14 minutes 51 seconds equals 891 seconds, which is 891/3600 of a degree or .2475 degree. For simplicity, let's telephone call that ¼ of a degree. Therefore, the bending in question is 63¼ degrees. Every bit shown in the in a higher place article, 63¼° multiplied by (π/180) = ane.1 radians.

Question
What is 1085 degrees in radian form?
1085° = 6.0277 radians. 1080° is equivalent to three complete circles, 1085° is the same angle equally 5° and 0.0277 radian.

Question
How do I convert radians into degrees?
Multiply the number of radians by 180°. For instance, two radians equal 360°. 5 radians equal 900°.
-
Question
What is 22550 degrees in radians course?
In general, multiply degrees by 0.0175 to get radians (1,691.25 radians in this instance). If you prefer to treat multiple full circles (equally in this case) equally less than a full circumvolve, first dissever the total degrees by 360 (the number of degrees in a total circle). 22,550 divided past 360 is 62 with a remainder of 230, which is the number of degrees beyond 62 full circles contained in 22,550°. Multiply 230 by 0.0175 to get the radians in one partial circle.
-
Question
What if the degree is negative?
That simply means the angle is being measured in a counter-clockwise direction, but the size of the angle (whether measured in degrees or radians) is the same equally if it were positive.
-
Question
How do I summate 90 degrees into radians?
Since 90° is ¼ of a circle, information technology'south also ¼ of 2π radians, or (π/2) radians.

Question
Why is pi causeless 22/7?
Because sometimes a fraction is easier to piece of work with than a decimal is, and 22/7 is the fraction that well-nigh closely approximates the value of pi.

Question
How do I find the degree measure of iii pi radian?
Multiply each π radian by 180°. 3 x 180° = 540°. That's 1½ total circles, which for applied purposes is equivalent to i one-half-circumvolve.

Article Summary X
To convert degrees to radians, accept the number of degrees to be converted and multiply it by π/180. Yous can calculate this past converting both numbers into fractions. For example, to convert 120 degrees you lot would have 120 ten π/180 = 120π/180. Once you've gotten your reply, simplify the radians. For more examples of converting degrees to radians, scroll down!
