The result of converting 130 degrees to radians is approximately 2.2689 radians.
To convert degrees into radians, multiply the degree value by π divided by 180. This works because a full circle of 360 degrees equals 2π radians, so a simple ratio allows us to switch between the two units.
Conversion Result
130 degrees equals about 2.2689 radians when rounded to four decimal places.

Conversion Formula
The formula to convert degrees into radians is radians = degrees * (π / 180). This formula is based on the fact that 180 degrees equals π radians, so multiplying degrees by this ratio converts the measurement into radians. For example, 130 degrees:
- Multiply 130 by π/180
- 130 * 3.1416 / 180
- = 408.408 / 180
- = 2.2689 radians
Conversion Example
- Convert 90 degrees to radians:
- Multiply 90 by π/180
- 90 * 3.1416 / 180
- = 282.744 / 180
- = 1.5708 radians
- Convert 45 degrees to radians:
- Multiply 45 by π/180
- 45 * 3.1416 / 180
- = 141.372 / 180
- = 0.7854 radians
- Convert 180 degrees to radians:
- Multiply 180 by π/180
- 180 * 3.1416 / 180
- = 565.488 / 180
- = 3.1416 radians
- Convert 0 degrees to radians:
- Multiply 0 by π/180
- 0 * 3.1416 / 180
- = 0

Conversion Definitions
Degrees
Degrees are a measurement of angles where a full circle equals 360 degrees. They are used to describe the size of an angle in a circle, with each degree representing 1/360th of the entire circle’s circumference.
Radians
Radians are a way to measure angles based on the radius of a circle, where one radian is the angle at which the arc length equals the radius. There are 2π radians in a full circle, linking linear and angular measurements directly.
Conversion FAQs
Why is π used in the degree to radian conversion?
π appears because it relates to the half-turn of a circle, where 180 degrees equals π radians. This constant bridges the linear measure of the circle’s arc with the angular measure, making it essential for accurate conversion.
Can I convert degrees to radians without π?
While π is integral to the conversion formula, you can perform calculations using an approximation of π, like 3.1416, for practical purposes. However, the exact conversion involves multiplying by π over 180.
How precise is the conversion from degrees to radians?
The precision depends on how accurately π is represented in calculations. Using more decimal places for π increases the precision, but for most purposes, 3.1416 or 3.14159265 is sufficient.
Is there an easier way to remember the degrees to radians formula?
Remember that 180 degrees equals π radians. So, to convert, just multiply by π/180. It simplifies to a straightforward ratio, making the calculation quick and easy once you memorize the key fact.
What are common radian measures for angles in degrees?
Angles like 90°, 180°, 270°, and 360° correspond to π/2, π, 3π/2, and 2π radians respectively. These serve as reference points for understanding the relationship between degrees and radians.
