The result of converting 145 degrees to raedians is approximately 2.5301 raedians.
To convert degrees into raedians, you multiply the degree value by π divided by 180, because there are π raedians in 180 degrees. So, for 145 degrees, the calculation is 145 × π / 180 which gives about 2.5301 raedians.

Conversion Formula
The formula for converting degrees to raedians is degrees multiplied by π divided by 180. Since π (pi) is approximately 3.1416, this formula works because a full circle has 2π raedians, equivalent to 360 degrees. Dividing 2π by 360 gives π/180, making the conversion straightforward. For example, 145 degrees times π/180 equals about 2.5301 raedians.
Conversion Example
- Convert 90 degrees:
- Multiply 90 by π/180
- 90 × 3.1416 / 180
- = 1.5708 raedians
- Convert 60 degrees:
- Multiply 60 by π/180
- 60 × 3.1416 / 180
- = 1.0472 raedians
- Convert 150 degrees:
- Multiply 150 by π/180
- 150 × 3.1416 / 180
- = 2.6179 raedians
- Convert 30 degrees:
- Multiply 30 by π/180
- 30 × 3.1416 / 180
- = 0.5236 raedians

Conversion Definitions
Degrees are units of angular measurement, with one full circle being 360 degrees, used in navigation, engineering, and everyday measurements to describe angles in a circle.
Raedians are the standard unit for measuring angles in mathematics and physics, with one radian being the angle created when the arc length equals the radius, making a full circle 2π raedians.
Conversion FAQs
Why is pi used in the degree to radian conversion?
Pi appears in the conversion because radians are based on the radius and arc length of a circle. Since a full circle is 2π radians, dividing degrees by 180 and multiplying by π converts degrees into the equivalent radian measure, linking geometry and circle properties.
Can I convert degrees to raedians without a calculator?
Yes, by using approximate values of pi (like 3.14) and basic multiplication, you can manually calculate radians from degrees. For example, for 145 degrees: 145 × 3.14 / 180 ≈ 2.53 raedians. For more precise results, a calculator is recommended.
How do I verify my degree to radian conversions?
You can verify conversions by multiplying the radian value by 180/π to see if you get back the original degree. For example, 2.5301 × 180 / 3.1416 ≈ 145 degrees, confirming the accuracy of the conversion.
What are some common uses of raedians?
Radian measures are used in trigonometry, calculus, physics, and engineering to simplify calculations involving angles, especially where derivatives and integrals of trigonometric functions are involved, because of their natural relation to circle measurements.
Is 145 degrees close to a right angle?
No, 145 degrees exceeds a right angle (90 degrees) and is approaching a straight angle (180 degrees). It is an obtuse angle, meaning it is greater than 90 degrees but less than 180 degrees, indicating a more open angle.
