130 degrees equals approximately 2.2689 radians.
To convert degrees to radians, multiply the degree value by π divided by 180. This works because a full circle is 2π radians, which equals 360 degrees. So, for 130 degrees, the calculation is 130 × π / 180, giving the radian measure.
Conversion Result
130 degrees equals 2.2689 radians when rounded to four decimal places.

Conversion Formula
The formula to convert degrees to radians is radians = degrees × π / 180. This formula works because the circumference of a circle is 2π radians, which equals 360 degrees. Dividing by 180 scales the degree measure into radians by the proportion of π to 180.
Example: for 130 degrees, multiply 130 by π (approximately 3.1416), then divide by 180: (130 × 3.1416) / 180 = 407.408 / 180 ≈ 2.2689 radians.
Conversion Example
- Convert 90 degrees:
- Step 1: Multiply 90 by π: 90 × 3.1416 ≈ 282.744
- Step 2: Divide by 180: 282.744 / 180 ≈ 1.5708 radians
- Convert 45 degrees:
- Step 1: 45 × 3.1416 ≈ 141.372
- Step 2: 141.372 / 180 ≈ 0.7854 radians
- Convert 180 degrees:
- Step 1: 180 × 3.1416 ≈ 565.488
- Step 2: 565.488 / 180 ≈ 3.1416 radians
- Convert 60 degrees:
- Step 1: 60 × 3.1416 ≈ 188.496
- Step 2: 188.496 / 180 ≈ 1.0472 radians

Conversion Definitions
Degrees are units measuring angles, where a full circle equals 360 degrees, dividing a circle into 360 parts. Radians are the standard angular measurement based on the radius and arc length, where one radian is the angle subtended by an arc equal in length to the radius.
Radians express angles as a fraction of the circle’s radius, providing a direct measure of the arc length per radius unit, unlike degrees which divide the circle into 360 equal parts.
Conversion FAQs
Why is it useful to convert degrees to radians?
Converting degrees to radians is important in mathematics and physics because many formulas, especially in trigonometry and calculus, are based on radian measures, which lead to more straightforward calculations and interpretations.
Can I convert any degree value to radians using this method?
Yes, the same formula applies to any degree value: multiply the degrees by π/180. It works universally, whether the degrees are whole numbers or decimals, to get the corresponding radian measure.
What if I need to convert radians back to degrees?
To reverse, multiply the radian value by 180/π. This allows you to find the degree equivalent of a given radian measure, making conversions bidirectional between these two units.
Are there any online tools for these conversions?
Yes, many online calculators and conversion tools exist that can quickly and accurately convert between degrees and radians without manual calculation, helpful for quick references or complex problems.
