155 degrees are sometimes abbreviated as 155 deg, and using the degree symbol written as 155°. The result in radian can be abbreviated with the unit symbol rad.
So, if you want to calculate 155 deg in rad or 155° to radians, then you are right here, too, because these are two common short forms for the unit transformation under consideration.
In this article you can find everything about it, including the formula and a calculator you don’t want to miss.

In the next section of this post we explain the conversion factor π/180°.
Convert 155 Degrees to Radians
Divide the angle in degrees by 180°, then multiply the term by π using thisFormula: rad = ([155°] / 180°) × π.
Thus, the converted angle in radians (rounded to ten decimal places) is:

Frequently Asked Questions
In in connection with this post, here are the FAQs. Do you know the correct answer?How do you convert 155 degrees to radians?
Divide the degrees by 180°, then multiply the term by π: 155°/180° × π = 31π/36 rad.
What is 155 degrees in radians in terms of pi?
155° in radians = 155°/180° × pi = 31/36 times pi.
How many radians is 155 degrees?
As one full circle of 360 degrees equals 2pi, 155 degrees = 155/360 × 2pi = 31/36 pi rad.
How many π’s is 155 degrees?
155° = 31/36 π.
What is 155 degrees in radians?
155° = 2.7052603406 rad.
What quadrant is 155 degrees?
Because each quadrant has 90 degrees we divide 155° by 90° = 1.7222222222, then round this term modulo 4 up to nearest whole number between 0 and 4: 2. Thus, 155° rad lies in the second quadrant between 90° and 180°.
What’s smaller 155 radian or 155 degrees?
A circle has a little more than 6 radians, yet 360 degrees. Thus, 155 degrees is much smaller than 155 radians.
How do I convert 155 degrees to radians in fraction form?
Rad = 155°/180° × π

Summary
You have reached the concluding section of our information about 155 deg in rad.155 degrees = 2.7052603406 rad
Using our converter, formula, chart and information, you have everything to convert degrees to radians at your disposal.
If you have found our post searching for hundred and fifty-five degrees to radians in terms of pi, or a similar term such as angle to radians, then you have gotten your answer as well: 155° ⇔ 2.7052603406 rad.
The radian measure is the standard unit of measure in the areas of math involving a circle like the sine function and cosine function, just to name a few.
Likewise in science, mathematical computations involving the angle of circle of some sort are hardly ever calculated in degrees.
Conversely, in plane geometry an angle in a circle or in a triangle is more likely to expressed in °.
Additional information
Last, but not least, here are some supplementary information related to the degree measurement and conversion:The positive movement of an angle in a circle is a counterclockwise revolution, and the angular measure is indicated in either of these units: deg, rad or grad.
The angle in degrees indicates how far you have tilted your head, whereas the angle in radians tells you how far you have traveled on the arc.
Calculations in radians are said to be easier, though. At least once you got the hang of it.
Typical usage for angles in radians include the sine function and cosine function, whereas the angle in a triangle is usually denoted in degree.
More information about radians & degrees, the entire circle including the radius, the circumference as well as the the definition of radian as ratio can be found in our article degrees to radians.
