270 degrees equals approximately 4.7124 radians.
To convert 270 degrees to radians, use the formula: radians = degrees × (π / 180). Since π is approximately 3.1416, multiplying 270 by (π / 180) gives the result. This conversion works because a full circle of 360 degrees equals 2π radians, so degrees are scaled by this ratio to radians.
Conversion Result
270 degree is equal to 4.7124 radian.

Conversion Formula
The conversion formula from degree to radian is radians = degrees × (π / 180). This works because a circle has 2π radians and 360 degrees, so dividing π by 180 gives the conversion factor. For example, 180 degrees times (π / 180) equals π radians, which is half a circle.
Conversion Example
- Convert 90 degrees:
- Apply formula: 90 × (π / 180)
- Calculate: 90 / 180 = 0.5
- Multiply by π: 0.5 × 3.1416 = 1.5708 radians
- Answer: 90 degrees = 1.5708 radians
- Convert 45 degrees:
- Apply formula: 45 × (π / 180)
- Calculate: 45 / 180 = 0.25
- Multiply by π: 0.25 × 3.1416 = 0.7854 radians
- Answer: 45 degrees = 0.7854 radians
- Convert 120 degrees:
- Apply formula: 120 × (π / 180)
- Calculate: 120 / 180 = 0.6667
- Multiply by π: 0.6667 × 3.1416 = 2.0944 radians
- Answer: 120 degrees = 2.0944 radians

Conversion Definitions
Degree
A degree is a unit of measurement for angles, where one full circle is divided into 360 equal parts, each called a degree. It is used in geometry, navigation, and various fields to quantify the size of angles.
Radian
A radian is an angle measurement based on the radius of a circle, where one radian equals the angle at the circle’s center subtended by an arc equal in length to the radius. It provides a natural measure for angular calculations, especially in trigonometry.
Conversion FAQs
How does multiplying by π/180 convert degrees to radians?
Multiplying degrees by π/180 scales the degree measure by the ratio of radians to degrees, since 360 degrees equals 2π radians. This ratio ensures the angle’s size is correctly converted, maintaining the same geometric value in radians.
Can I use a calculator to convert 270 degrees to radians directly?
Yes, most scientific calculators have a mode for degree/radian conversions or can perform the multiplication directly. Just input 270 × π / 180 to get approximately 4.7124 radians, or use the built-in conversion feature if available.
Why is 270 degrees equal to 3π/2 radians?
Because 3π/2 radians is equivalent to 270 degrees, as both measure the same angle in different units. The conversion stems from the fact that 180 degrees equals π radians, so 270 degrees equals (270/180)×π = 3π/2 radians.
