2.5 degrees is approximately 0.0436 radians.
To convert degrees to radians, multiply the degree value by π divided by 180. Since π is roughly 3.1416, you get the radian equivalent by this simple formula. This process works because a full circle (360°) equals 2π radians, so degrees are scaled accordingly.
Conversion Result
The conversion of 2.5 degrees to radians results in approximately 0.0436 radians.

Conversion Formula
The formula to convert degrees to radians is radians = degrees × π / 180. This works because a full circle of 360 degrees equals 2π radians, so dividing by 180 adjusts the scale from degrees to radians. For example, 45° × π / 180 = π/4 radians, about 0.7854.
Conversion Example
- Convert 10 degrees:
- Multiply 10 by π/180.
- 10 × 3.1416 / 180 ≈ 0.1745 radians.
- Convert 15 degrees:
- 15 × 3.1416 / 180 ≈ 0.2618 radians.
- Convert 30 degrees:
- 30 × 3.1416 / 180 ≈ 0.5236 radians.

Conversion Definitions
Deg (degrees) is a unit of angular measurement representing 1/360th of a full circle, used widely in navigation, geometry, and daily references. Rad (radian) is an angle measure where one radian equals the angle at the center of a circle subtended by an arc equal in length to the radius.
Conversion FAQs
Why is the conversion from degrees to radians necessary?
Converting degrees to radians is essential because many mathematical functions, especially in calculus and trigonometry, work directly with radians, providing more accurate and natural measurements for angular calculations.
Can I convert degrees to radians without a calculator?
Yes, by multiplying the degree value by π/180. For simpler angles, you can memorize common radian equivalents, but for arbitrary degrees like 2.5, a calculator makes the process straightforward and precise.
What is the significance of π in the conversion?
π appears because a full circle is 2π radians and 360 degrees. This constant bridges the two units, making the formula a direct proportionality between degrees and radians based on this fundamental relationship.
Are there other units similar to radians for measuring angles?
Yes, degrees are most common, but in specialized fields, units like gradians or turns are used, where a turn equals 360 degrees, and gradians divide a circle into 400 parts. Radians remain the standard in mathematical contexts for their natural properties.
