The conversion of 165 degrees to radians result in approximately 2.8798 radians.
This conversion is based on the fact that 180 degrees equals π radians, so to convert degrees to radians, you multiply the degree value by π over 180. For 165 degrees, the calculation is 165 × π / 180, which equals approximately 2.8798 radians.
Conversion Result
165 degrees is equivalent to about 2.8798 radians.

Conversion Formula
The formula to convert degrees to radians is radians = degrees × π / 180. This works because a full circle has 360 degrees and 2π radians, so dividing π by 180 creates a factor that converts degrees into radians. For example, 165 degrees times π divided by 180 equals approximately 2.8798 radians.
Conversion Example
- Convert 90 degrees to radians:
- Multiply 90 by π / 180, which is 90 × 3.1416 / 180.
- Calculates to 1.5708 radians.
- Convert 45 degrees to radians:
- Multiply 45 by π / 180, which is 45 × 3.1416 / 180.
- Equals approximately 0.7854 radians.
- Convert 180 degrees to radians:
- Multiply 180 by π / 180, which simplifies to π.
- Result is about 3.1416 radians.

Conversion Definitions
Degrees
Degrees are units used to measure angles, where a full circle contains 360 degrees. It is a common way to quantify the size of an angle, with 0° indicating no angle and 360° representing a complete rotation.
Radians
Radians are units for measuring angles based on the radius of a circle, where one radian equals the angle at the center of a circle that subtends an arc equal in length to the radius. A full circle has 2π radians, making it a natural measurement system for math.
Conversion FAQs
Why is π used in the degrees to radians conversion?
π appears in the conversion because it is the mathematical constant relating the circumference and diameter of a circle, and radians measure angles based on the circle’s radius. The full circle is 2π radians, aligning with 360 degrees, making π the natural factor for conversion.
What happens if I input 0 degrees into the converter?
If you input 0 degrees, the converter shows 0 radians because zero degrees indicates no angle or rotation, which corresponds to zero radians. This is a straightforward conversion where the result is always zero for zero degrees.
Can I convert negative degrees to radians using this tool?
Yes, the tool accepts negative degrees, and it will calculate the corresponding negative radians, indicating a rotation in the opposite direction. For example, -165 degrees converts to approximately -2.8798 radians.
Is the conversion from degrees to radians always precise?
The conversion is exact mathematically, but the displayed result is rounded to four decimal places for simplicity. The actual value of π is irrational, so some results are approximations, but they are sufficiently accurate for most purposes.
