The conversion of 2.5 degrees to radians is approximately 0.0436 rad.
To convert degrees to radians, multiply the degree value by π divided by 180. Since 1 degree equals π/180 radians, multiplying 2.5 by π/180 gives the result in radians, which is about 0.0436. This conversion is used in mathematics and physics when working with angles in different units.

Conversion Formula
The formula to convert degrees (deg) to radians (rad) is rad = deg * (π / 180). It works because a full circle is 360 degrees or 2π radians, therefore, dividing π by 180 scales degrees to radians. For example, converting 2.5 deg:
- Multiply 2.5 by π (approximately 3.1416): 2.5 * 3.1416 = 7.854
- Divide 7.854 by 180: 7.854 / 180 ≈ 0.0436 rad
Conversion Example
- Convert 10 degrees:
- Multiply 10 by π: 10 * 3.1416 = 31.416
- Divide 31.416 by 180: 31.416 / 180 ≈ 0.1745 rad
- Convert 45 degrees:
- Multiply 45 by π: 45 * 3.1416 = 141.372
- Divide 141.372 by 180: 141.372 / 180 ≈ 0.7854 rad
- Convert 90 degrees:
- Multiply 90 by π: 90 * 3.1416 = 282.744
- Divide 282.744 by 180: 282.744 / 180 ≈ 1.5708 rad
- Convert 0 degrees:
- 0 * π / 180 = 0 rad

Conversion Definitions
deg
Deg, short for degrees, is a unit of angular measurement representing 1/360th of a full circle, used in geometry and navigation to specify angles and directions.
rad
Rad, short for radians, is a unit of angular measurement based on the radius of a circle, where one radian equals the angle at which the arc length equals the radius, used in higher mathematics and physics for precision.
Conversion FAQs
Why is the conversion from degrees to radians necessary?
This conversion is essential because many mathematical formulas, especially in calculus and trigonometry, require angles in radians for accurate calculations and simplicity in equations involving sine, cosine, and tangent functions.
How accurate is the conversion of 2.5 degrees to radians?
The conversion result of approximately 0.0436 radians is precise up to four decimal places, suitable for most calculations. For higher precision, you can keep more decimal points in π, but for everyday use, this level is sufficient.
Can I convert other degree values to radians using the same method?
Yes, the same formula applies universally: multiply the degree value by π/180. This method works for any degree measure, whether positive or negative, to find its radian equivalent.
