165 degrees is approximately 2.88 radians.
Converting 165 degrees to radians involves multiplying the degree value by π/180 because there are π radians in 180 degrees. This conversion is necessary because degrees and radians are two different units for measuring angles. The formula makes sure we get the equivalent angle in radians.
Conversion Result
165 degrees equals approximately 2.88 radians.
To convert degrees into radians, we multiply the degree value by π divided by 180. So, 165 multiplied by π/180 gives the radians. This works because π radians equal 180 degrees. It’s a direct proportion between the two units, allowing us to switch from degrees to radians efficiently.

Conversion Formula
The formula for converting degrees to radians is multiplying the degree angle by π/180. Since 180 degrees is equal to π radians, this ratio allows us to switch between the units. For example, converting 165 degrees: 165 × π/180 = 2.88 radians. This ensures the angle’s measure remains consistent in different units.
Conversion Example
- Convert 90 degrees to radians:
- Multiply 90 by π/180
- 90 × π/180 = π
- Result: π radians, which is approximately 3.14
- Convert 45 degrees to radians:
- Multiply 45 by π/180
- 45 × π/180 = π/4
- Result: approximately 0.7854 radians
- Convert 180 degrees to radians:
- Multiply 180 by π/180
- 180 × π/180 = π
- Result: π radians, about 3.14
- Convert 30 degrees to radians:
- Multiply 30 by π/180
- 30 × π/180 = π/6
- Result: approximately 0.5236 radians

Conversion Definitions
Degrees
Degrees are a unit of angular measurement where a full circle equals 360 degrees. Used in navigation, geometry, and everyday measurements, degrees divide a circle into 360 equal parts, making it a familiar way to specify angles.
Radians
Radians measure angles based on the radius of a circle, defining the angle as the length of the arc divided by the radius. One radian is the angle where the arc length equals the radius, with a full circle being 2π radians, linking it directly to the circle’s properties.
Conversion FAQs
Why is π used in the degrees to radians conversion?
π appears because it relates directly to the properties of a circle; 180 degrees equals π radians. Using π in the formula provides an accurate ratio between the two units, ensuring precise conversion of angles between degrees and radians.
Can I convert any degree measure to radians using this method?
Yes, multiplying the degree value by π/180 will always give the correct radian measure, regardless of the angle. This formula applies universally to all degree values, whether small or large.
What is the significance of 165 degrees in radians?
165 degrees corresponds to 2.88 radians, which is more than π but less than 3π/2. It indicates an angle slightly less than a right angle, useful in trigonometry, physics, and engineering calculations involving angles.
