Conversion Formula
The formula to convert degrees to radians is: radians = degrees × (π / 180). This works because a full circle is 360 degrees or 2π radians. Dividing π by 180 converts degrees into a proportional part of a radian. For example, 2.5° × (π / 180) equals approximately 0.0436 rad.
Conversion Example
- Convert 10 degrees to radians:
- Multiply 10 by π/180.
- 10 × (3.1416 / 180) ≈ 0.1745 rad.
- Convert 45 degrees to radians:
- 45 × (π / 180).
- 45 × 0.01745 ≈ 0.7854 rad.
- Convert 90 degrees to radians:
- 90 × (π / 180).
- 90 × 0.01745 ≈ 1.5708 rad.
- Convert 15 degrees to radians:
- 15 × (π / 180).
- 15 × 0.01745 ≈ 0.2618 rad.
- Convert 0 degrees to radians:
- 0 × (π / 180) = 0 rad.

Conversion Definitions
deg
Deg, short for degrees, is a unit measuring angles where a full circle equals 360 degrees. It’s used in navigation, geometry, and everyday contexts to describe the size of angles or rotations.
rad
Rad, short for radians, is an angle measure based on the radius of a circle. One radian equals the angle subtended by an arc equal in length to the circle’s radius, making it essential in higher mathematics and physics calculations.
Conversion FAQs
What is the significance of converting 2.5 degrees to radians in scientific calculations?
Converting 2.5 degrees to radians is crucial because many equations in physics and engineering are formulated in radians. Using radians ensures the calculations involving trigonometric functions are accurate and consistent with mathematical standards.
Why do angles in mathematics often use radians instead of degrees?
Radians are preferred because they relate directly to the properties of circles, simplifying calculus and trigonometric function derivatives. They provide a natural measure of angles, making formulas more elegant and calculations easier.
Can I use a calculator to convert 2.5 degrees to radians?
Yes, most scientific calculators have a function to convert degrees to radians, or you can manually multiply 2.5 by π/180. This direct calculation gives the precise radian value needed for advanced computations.
What is the importance of the π/180 factor in the conversion?
The factor π/180 converts degrees into a fraction of a circle expressed in radians, since 180 degrees equals π radians. This proportional relationship is fundamental in converting between these two units accurately.
