145 degrees equals approximately 2.5302 raedians.
To convert degrees to raedians, multiply the degree value by π divided by 180. Since 1 degree equals π/180 raedians, for 145 degrees, the calculation is 145 × π/180, resulting in about 2.5302 raedians.

Conversion Formula
The formula to convert degrees to raedians involves multiplying the degrees by π/180 because raedians measure angles based on the radius of a circle. Since 180 degrees equals π raedians, dividing π by 180 standardizes degrees into raedians. For example, 145° × π/180 ≈ 2.5302 raedians.
This works because the radian is a measure of the angle created at the center of a circle by an arc equal in length to the radius. Multiplying degrees by π/180 converts the degree measure into this radian ratio.
Conversion Example
- Convert 90 degrees to raedians:
- Step 1: Write the formula: 90 × π/180
- Step 2: Simplify: 90/180 = 0.5
- Step 3: Multiply by π: 0.5 × π = 1.5708 raedians
- Convert 60 degrees to raedians:
- Step 1: 60 × π/180
- Step 2: 60/180 = 0.3333
- Step 3: 0.3333 × π ≈ 1.0472 raedians
- Convert 180 degrees to raedians:
- Step 1: 180 × π/180
- Step 2: 180/180 = 1
- Step 3: 1 × π = 3.1416 raedians

Conversion Definitions
Degrees
Degrees are units measuring angles based on dividing a circle into 360 equal parts. They help specify the size of an angle relative to a full rotation, where 360 degrees equals a complete circle.
Raedians
Raedians are units for measuring angles based on the radius of a circle, where one radian equals the angle created at the circle’s center by an arc equal in length to the radius. There are 2π raedians in a full circle.
Conversion FAQs
Why is π used in the degrees to raedians conversion?
π appears because raedians are defined via the circle’s properties, specifically relating an arc length to the radius. Since a full circle’s angle in raedians is 2π, using π in calculations simplifies the conversion from degrees to raedians.
Can I convert degrees to raedians without a calculator?
Yes, by memorizing common conversions like 180° = π radians, you can estimate or approximate other conversions. For precise results, a calculator or computational tool helps to multiply the degree value by π/180 accurately.
What is the significance of 145 degrees in radians?
145 degrees converts to approximately 2.5302 raedians, which is useful in various mathematics, physics, and engineering calculations involving angles, especially in contexts requiring radian measurements for trigonometry or circular motion.
How do I manually convert any degree measurement to raedians?
Multiply the degree value by π/180. For example, for 145 degrees: 145 × π/180. Simplify if possible, then multiply out to get the radian measure. This method works universally for all degree-to-radian conversions.
Is the conversion from degrees to raedians linear?
Yes, the conversion is linear because it involves multiplying by a constant factor (π/180), meaning each degree increases proportionally in raadians.
