-171 Degrees in Radians

Welcome to -171 degrees in radians, our post explaining the conversion of this angle from the unit degree to the unit circle frequently used in trigonometric functions.

Skip intro and head directly to the result.

Negative 171 degrees are sometimes abbreviated as -171 deg, and using the degree symbol written as -171°. The result in radian can be abbreviated with the unit symbol rad.

So, if you want to calculate -171 deg in rad or -171° 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.

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

In the next section of this post we explain the conversion factor π/180°.

Convert -171 Degrees to Radians

Divide the angle in degrees by 180°, then multiply the term by π using this

Formula: rad = ([-171°] / 180°) × π.

Thus, the converted angle in radians (rounded to ten decimal places) is:

-171° = -(19/20)×π rad = -19π/20 rad ≈ -2.9845130209 rad

If you need the outcome with higher accuracy, then make use of our calculator above, or employ a calculator of your own and our formula.

Frequently Asked Questions

In in connection with this post, here are the FAQs. Do you know the correct answer?

How do you convert -171 degrees to radians?

Divide the degrees by 180°, then multiply the term by π: -171°/180° × π = -19π/20 rad.

What is -171 degrees in radians in terms of pi?

-171° in radians = -171°/180° × pi = -19/20 times pi.

How many radians is -171 degrees?

As one full circle of 360 degrees equals 2pi, -171 degrees = -171/360 × 2pi = -19/20 pi rad.

How many π’s is -171 degrees?

-171° = -19/20 π.

What is -171 degrees in radians?

-171° = -2.9845130209 rad.

What quadrant is -171 degrees?

Because each quadrant has 90 degrees we divide the coterminal angle of -171° by 90°: 189°/90° = 2.1, then round this term up to nearest whole number between 0 and 4: 3. Thus, -171° rad lies in the third quadrant between 180° and 270°.

What’s smaller -171 radian or -171 degrees?

A circle has a little more than 6 radians, yet 360 degrees. Thus, -171 degrees is much smaller than -171 radians.

How do I convert -171 degrees to radians in fraction form?

Rad = -171°/180° × π

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.
