Conversion Formula
The conversion from degrees to radians is based on the fact that a full circle has 2π radians and 360 degrees. Therefore, 1 degree equals π/180 radians. Multiplying degrees by π/180 gives the equivalent in radians, which works because of the proportional relationship.
For example, for 102 degrees: 102 * π/180 = (102/180) * π = 0.5667 * 3.1416 ≈ 1.78 radians.
Conversion Example
- Convert 45 degrees:
- 45/180 = 0.25
- 0.25 * π ≈ 0.7854 radians
- Convert 90 degrees:
- 90/180 = 0.5
- 0.5 * π ≈ 1.5708 radians
- Convert 150 degrees:
- 150/180 ≈ 0.8333
- 0.8333 * π ≈ 2.6179 radians
- Convert 200 degrees:
- 200/180 ≈ 1.1111
- 1.1111 * π ≈ 3.4907 radians
- Convert 270 degrees:
- 270/180 = 1.5
- 1.5 * π ≈ 4.7124 radians

Conversion Definitions
Degrees: A unit of angular measurement where a full circle is divided into 360 equal parts, each called a degree, used in navigation, geometry, and daily angles.
Radians: The standard unit of angular measure based on the radius of a circle, where one radian equals the angle at which the arc length equals the radius, making it fundamental in mathematics and physics calculations.
Conversion FAQs
Why is the conversion factor π/180 used?
The factor π/180 stems from the fact that 180 degrees equal π radians, making it the proportional constant to switch between degrees and radians. Multiplying degrees by π/180 converts the measure into radians because of this relationship.
Can I convert degrees to radians without a calculator?
Yes, by knowing that 1 degree equals π/180 radians, you can perform mental math or estimate by multiplying the degree value by approximately 0.01745. For precise results, a calculator or software is recommended.
What are some common angles in radians?
Angles like 30°, 45°, 60°, 90°, and 180° convert to approximately 0.5236, 0.7854, 1.0472, 1.5708, and π radians respectively, often used in geometry and trigonometry problems for their simplicity in calculations.
