2π/3 Radians in Degrees

  • by

Welcome to 2π/3 radians in degrees, our post explaining the angle conversion from radian to degrees measure commonly used in trigonometric functions.

The arc length of (2/3)×π in a circle, that is the angle in radians, is usually abbreviated as 2π/3 rad, and degrees are commonly written with the degree symbol °.

Skip intro and head directly to the result.

So, if you have been looking for 2π/3 rad in deg or 2π/3 rad to °, 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.

Our app can change both, radians to degree measure as well as degrees to radians, and our tool even accepts “π”, “pi”, “Pi” and “PI” as input. Give it a go, now!

Convert 2π/3 Radians to Degrees

Divide the angle in rad by π, then multiply the term by 180° using the formula deg = ([2π/3] / π) × 180°. Thus, you get (rounded to ten decimal places):

2π/3 rad = 120°

Frequently Asked Questions

What is 2π/3 radians in terms of pi?

An angle of 2π/3 radians cuts off an arc of length 2π/3r when placed at the center of a circle with the radius r; the relationship with pi can only be determined if the angle in degrees is known: 2π/3 rad = degrees / 180° x pi.

Where is 2π/3 radians on unit circle?

The angle of 2π/3 radians lies in the second quadrant, between pi/2 and pi.

What is the angle measure of 2π/3 radians?

2π/3 exact radians is equal to 2π/3 / π × 180° = 120°.

How many degrees in 2π/3 radians?

2π/3 rad = 2π/3 / π × 180° = 120 degrees.

What’s bigger 2π/3radian or 2π/3 degree?

A circle has a little more than six radians, yet 360 degrees. Thus, 2π/3 radians much bigger than 2π/3 degrees.

What is 2π/3 radians converted to degrees?

2π/3 radians converted to degrees equals 120 degrees.

How to convert 2π/3 radians to degrees?

To convert 2π/3 radians to degrees divide the angle in radians by pi, then multiply the term by 180°: degreees = 2π/3/ π × 180°.

What quadrant is 2π/3 radians?

Because each quadrant has π/2 radians we divide 2π/3 by π/2 = 1.33333333333333, then round this term modulo 4 up to nearest whole number between 1 and 4: 2. Thus, 2π/3 rad lies in the second quadrant.

Additional information

The positive movement of an angle in a circle is a counterclockwise revolution, and the angular measure is indicated in either of these units: rad, deg or grad (gradians).

The magnitude in radians tells you how far you have traveled on the arc. Try to remember that whenever you deal with radians or the other circular measure.

More information about the term radian, the entire circle, the diameter as well as the complete revolution can be found in radians to degrees.
