540 degrees equals approximately 9.4248 radians.
To convert degrees to radians, multiply the degree value by π divided by 180. Since π is about 3.1416, you can also multiply the degrees directly by 0.0174533. For 540 degrees, (540 × π) / 180 = 3π, which is roughly 9.4248 radians.

Conversion Formula
The formula to convert degrees to radians is: radians = degrees × (π / 180). This works because a full circle has 2π radians and 360 degrees, so dividing 2π by 360 gives the conversion factor. Multiplying degrees by this factor gives radians. For example, 540 degrees:
- 540 × (π / 180)
- = 540 × 0.0174533
- = 9.4248 radians
Conversion Example
Convert 300 degrees to radians:
- Step 1: Write the formula: radians = degrees × (π / 180).
- Step 2: Substitute 300 for degrees: radians = 300 × (π / 180).
- Step 3: Simplify: 300 / 180 = 5 / 3.
- Step 4: Multiply: (5 / 3) × π ≈ 1.6667 × 3.1416 ≈ 5.23599.
- Result: 300 degrees ≈ 5.236 radians.

Conversion Definitions
Degrees
Degrees are units used to measure angles, where a full circle equals 360 degrees, dividing an angle into 360 equal parts, making it easy to describe the size of angles in a familiar, numerical way.
Radians
Radians are a unit for measuring angles based on the radius of a circle, where one radian is the angle subtended at the circle’s center by an arc equal in length to the radius. It provides a direct relation between the circle’s radius and arc length.
Conversion FAQs
Why is π used in the conversion between degrees and radians?
π appears because a full circle measures 2π radians and 360 degrees. The ratio π / 180 simplifies the conversion, linking the degree and radian measures based on the circle’s geometry.
Can I convert degrees to radians without a calculator?
Yes, by using the approximation π ≈ 3.1416 and multiplying the degree value by π / 180. For quick estimates, you can use 0.0174533 as the conversion factor for degrees to radians.
What does 3π radians represent in degrees?
Since 1 radian equals approximately 57.2958 degrees, 3π radians equals 3×π×(180/π) = 540 degrees. It indicates a semicircular angle covering half the circle.
Is converting degrees to radians necessary in all mathematics work?
Not always, but in calculus, trigonometry, and advanced geometry, radians are often required because they simplify formulas and calculations involving angles and arcs.
