150 degrees is approximately 2.6180 radians.
To convert degrees to radians, multiply the degree value by π divided by 180. Since 150° times π/180 equals 150π/180, which simplifies to 5π/6, the result is about 2.6180 radians. This conversion is based on the fact that 180 degrees equals π radians, so the ratio helps switch between units.
Conversion Result
150 degree equals approximately 2.6180 radians when converted.

Conversion Formula
The conversion from degree to radian uses the formula: radians = degrees × (π / 180). This formula works because a full circle has 360 degrees, which equals 2π radians. Dividing π by 180 scales degrees into radians, making the conversion accurate.
For example, converting 150 degrees: 150 × (π / 180) = (150 / 180) × π = 5/6 × π, which equals approximately 2.618 radians. This step-by-step process ensures precise results for any degree value.
Conversion Example
- Convert 90 degrees to radians:
- Step 1: Use the formula: radians = 90 × (π / 180)
- Step 2: Simplify: 90 / 180 = 1/2
- Step 3: Multiply: 1/2 × π = π/2
- Step 4: Approximate: π/2 ≈ 1.5708 radians
- Convert 45 degrees to radians:
- Step 1: 45 × (π / 180)
- Step 2: 45 / 180 = 1/4
- Step 3: 1/4 × π = π/4
- Step 4: Approximate: π/4 ≈ 0.7854 radians
- Convert 180 degrees to radians:
- Step 1: 180 × (π / 180)
- Step 2: 180 / 180 = 1
- Step 3: 1 × π = π
- Step 4: Approximate: π ≈ 3.1416 radians

Conversion Definitions
Degree
A degree is a unit of angle measurement that divides a circle into 360 equal parts, making it a common standard for measuring angles, directions, and rotations in geometry, navigation, and various sciences. One full circle equals 360 degrees.
Radian
A radian is an angle measurement based on the radius of a circle, where one radian equals the angle at which the arc length equals the radius. There are 2π radians in a full circle, making it a natural unit for mathematical calculations involving circles.
Conversion FAQs
Why do we use radians instead of degrees in mathematical calculations?
Radians provide a direct relationship between angles and arc lengths, simplifying many formulas in calculus and trigonometry. They make derivatives and integrals of trigonometric functions more straightforward, which is why they are preferred in higher-level mathematics.
How is 150 degrees related to the value of π?
Since 180 degrees equals π radians, 150 degrees is (150/180) of a full circle, which simplifies to 5/6. Multiplying this fraction by π gives 5π/6 radians, showing the direct relationship between degree measure and π.
Can I convert degrees to radians without a calculator?
Yes, by remembering the formula: radians = degrees × (π / 180). For common angles like 30°, 45°, 60°, and 90°, you can memorize their radian equivalents to save time and avoid calculations.
