0.2 Rad to Degrees – Answer and Calculator Tool

0.2 radians equals approximately 11.4592 degrees.

To convert radians to degrees, multiply the radian value by 180 and then divide by π (pi). This changes the measure from the radian unit, which is based on the radius of a circle, to degrees, which divides a circle into 360 parts.

Conversion Formula

The formula to convert radians to degrees is:

Degrees = Radians × (180 ÷ π)

This formula works because the full circle is 2π radians which equals 360 degrees. Dividing 360 degrees by 2π gives 180/π degrees per radian. Multiplying any radian value by 180/π gives its equivalent in degrees.

Example for 0.2 radians:

• Start with 0.2 radians
• Multiply by 180: 0.2 × 180 = 36
• Divide by π (about 3.1416): 36 ÷ 3.1416 ≈ 11.4592 degrees

Conversion Example

• Convert 1 radian to degrees:
  • 1 × 180 = 180
  • 180 ÷ 3.1416 ≈ 57.2958 degrees
  • Result: 1 rad = 57.2958°
• Convert 0.5 radians to degrees:
  • 0.5 × 180 = 90
  • 90 ÷ 3.1416 ≈ 28.6479 degrees
  • Result: 0.5 rad = 28.6479°
• Convert -1.2 radians to degrees:
  • -1.2 × 180 = -216
  • -216 ÷ 3.1416 ≈ -68.7549 degrees
  • Result: -1.2 rad = -68.7549°
• Convert 2.5 radians to degrees:
  • 2.5 × 180 = 450
  • 450 ÷ 3.1416 ≈ 143.2394 degrees
  • Result: 2.5 rad = 143.2394°

Conversion Definitions

Rad: Rad, short from radian, is a unit measuring angles based on radius length. One radian is the angle created when the arc length equals the radius of the circle. It’s widely used in math and science for angle measurement because it relates directly to circle geometry.

Degrees: Degrees measure angles by dividing a full circle into 360 equal parts. One degree equals 1/360th of a circle. Degrees are commonly used in everyday contexts like navigation, geometry, and engineering for expressing angles in a more intuitive way than radians.

Conversion FAQs

Why do we multiply radians by 180 and divide by π to get degrees?

Because a full circle has 2π radians and 360 degrees, the ratio between degrees and radians is 360 ÷ 2π = 180 ÷ π. Multiplying radians by 180/π changes the unit from radian to degrees based on this ratio.

Can radians be negative and what does negative degrees mean?

Yes, radians can be negative, indicating direction of rotation opposite to positive. Negative degrees mean the angle is measured clockwise or opposite to the positive angle direction, useful in trigonometry and rotations.

Is it necessary to use π value precisely for conversion?

Using π approximately as 3.1416 is enough for most practical calculations. For high precision, a more exact value or symbolic π is used. Slight variations in π approximation affect only very small decimal places.

How does this conversion apply to real-world situations?

Converting radians to degrees helps interpret angles in more familiar terms, like in navigation, physics, engineering, and graphics, where degrees are easier to understand than radians.

Can I convert degrees back to radians easily?

Yes, converting degrees to radians is done by multiplying degrees by π/180, reversing the formula to switch back from degrees to radians.
