58 degrees equals approximately 1.011 radian.
To convert degrees to radian, multiply the degree value by π divided by 180. For 58 degrees, the calculation is 58 × π / 180 ≈ 1.011 radian, since π is roughly 3.1416, making the conversion precise and straightforward for angles measured in degrees to be expressed in radians.
Conversion Result and Explanation
58 degrees in radians is about 1.011. This conversion is based on the fact that a full circle has 2π radians, which corresponds to 360 degrees. Therefore, converting degrees to radians involves scaling the degree measure to this full circle in radians.

Conversion Formula
The formula to convert degrees to radians is radians = degrees × (π / 180). This works because a full circle is 2π radians and 360 degrees, so dividing π by 180 effectively scales degrees into radians. For example, converting 60 degrees: 60 × π / 180 = π / 3 ≈ 1.0472 radians.
Conversion Example
- Convert 45 degrees to radians:
- Multiply by π / 180.
- 45 × π / 180 = π / 4.
- In decimal: 45 × 3.1416 / 180 ≈ 0.7854 radians.
- Convert 90 degrees:
- 90 × π / 180 = π / 2.
- Decimal: 90 × 3.1416 / 180 ≈ 1.5708 radians.
- Convert 120 degrees:
- 120 × π / 180 = 2π / 3.
- In decimal: 120 × 3.1416 / 180 ≈ 2.0944 radians.
- Convert 30 degrees:
- 30 × π / 180 = π / 6.
- Decimal: 30 × 3.1416 / 180 ≈ 0.5236 radians.

Conversion Definitions
Degrees
Degrees are units of measurement for angles, where a full circle equals 360 degrees. It divides a circle into 360 equal parts, used in everyday angle measurement, navigation, and geometry, providing a familiar way to specify angles.
Radian
Radian is an angular measurement based on the radius of a circle, where one radian equals the angle at the center subtended by an arc equal in length to the radius. There are 2π radians in a full circle, making it essential in advanced mathematics and physics.
Conversion FAQs
Why do we need to convert degrees to radians?
Converting degrees to radians is necessary because many mathematical functions, especially in calculus and trigonometry, use radians for accuracy and simplicity, as radians relate directly to the properties of circles and their arcs.
How precise is the conversion from degrees to radians?
The precision depends on the decimal approximation of π used. Using 3.1416 for π gives about four decimal places of accuracy, sufficient for most calculations, but higher precision can be achieved with more decimal points of π.
Can I convert any degree measure to radians using the same formula?
Yes, the formula radians = degrees × π / 180 applies universally to convert any degree measurement into radians, regardless of the size of the angle, making it a versatile and reliable method.
