145 degrees is approximately 2.5309 raedians.
To convert degrees to raedians, you multiply the degree value by π divided by 180. Since raadians are a way to measure angles based on the radius of a circle, this formula converts the angle in degrees into the equivalent measure in raedians, which are used in higher mathematics and engineering.

Conversion Formula
The formula to convert degrees to raedians is radians = degrees × (π / 180). This works because a full circle is 2π raadians, and a full circle in degrees is 360°. So, dividing π by 180 normalizes the degrees into raadians. For example, converting 60°:
- Multiply 60 by π: 60 × 3.1416 = 188.496
- Divide 188.496 by 180: 188.496 / 180 = 1.0472
- This results in approximately 1.0472 raadians.
Conversion Example
- Convert 90° to raadians:
- Multiply 90 by π: 90 × 3.1416 = 282.744
- Divide 282.744 by 180: 282.744 / 180 ≈ 1.5708
- Result is about 1.5708 raadians.
- Convert 45°:
- 45 × 3.1416 = 141.372
- Divide by 180: 141.372 / 180 ≈ 0.7854
- Answer: 0.7854 raadians.
- Convert 180°:
- 180 × 3.1416 = 565.488
- Divide by 180: 565.488 / 180 = 3.1416
- Answer: π raadians or approximately 3.1416.

Conversion Definitions
Degrees
Degrees are a unit of angular measurement, where a full circle is divided into 360 equal parts, each called a degree. It is used in geometry, navigation, and various fields to describe angles relative to a circle’s circumference.
Raedians
Raedians are a measure of angles based on the radius of a circle, where one raedian is the angle subtended at the center by an arc equal in length to the radius. There are 2π raedians in a full circle, making it useful in advanced mathematics and physics.
Conversion FAQs
Why is the formula to convert degrees to raedians multiplied by π / 180?
This fraction normalizes degrees to raedians because a circle has 2π raedians and 360 degrees. Dividing π by 180 converts the degree measure into the equivalent measure in raedians, aligning the angular units properly for calculations.
Can I convert any degree measure to raedians using this formula?
Yes, multiplying any degree value by π divided by 180 gives the corresponding raedian measure. This universal formula works for all angles, whether small or large, positive or negative.
What are some practical applications of converting degrees to raedians?
Engineers, mathematicians, and physicists often convert degrees to raedians when working with trigonometric functions, oscillations, wave analysis, and rotational dynamics, where raedian measures simplify calculations involving periodic phenomena.
