The conversion of 126 degrees to radians equals approximately 2.1981 radians.
Since 1 degree is equal to π divided by 180 radians, multiplying 126 degrees by π/180 gives the radians value. This conversion works because degrees and radians are both units for measuring angles, but radians are based on the radius of a circle, making the calculation precise and consistent.

Conversion Formula
The formula to convert degrees to radians is radians = degrees × (π / 180). This works because a full circle contains 2π radians, which corresponds to 360 degrees. Dividing 2π by 360 gives the radians per degree, so multiplying degrees by this factor converts to radians.
For example, for 126 degrees: 126 × (π / 180) = (126 / 180) × π = 0.7 × π ≈ 2.1981 radians, showing how the calculation transforms degrees into the more mathematically natural radian measure.
Conversion Example
- Convert 90 degrees to radians:
- Step 1: Write the formula: radians = 90 × (π / 180)
- Step 2: Simplify: 90 / 180 = 0.5
- Step 3: Multiply: 0.5 × π ≈ 1.5708 radians
- Result: 90 degrees equals approximately 1.5708 radians.
- Convert 45 degrees to radians:
- Step 1: Formula: 45 × (π / 180)
- Step 2: Simplify: 45 / 180 = 0.25
- Step 3: Multiply: 0.25 × π ≈ 0.7854 radians
- Result: 45 degrees equals approximately 0.7854 radians.
- Convert 180 degrees to radians:
- Step 1: Formula: 180 × (π / 180)
- Step 2: Simplify: 180 / 180 = 1
- Step 3: Multiply: 1 × π ≈ 3.1416 radians
- Result: 180 degrees equals exactly π radians.

Conversion Definitions
Degrees are a measurement of angles based on dividing a circle into 360 equal parts, making it easier to describe angles in everyday use and navigation.
Radians are a unit for measuring angles based on the radius of a circle, where one radian is the angle created when the arc length equals the radius, providing a natural measure for mathematical calculations involving circles.
Conversion FAQs
Why is converting degrees to radians important?
Converting degrees to radians is necessary because many mathematical formulas, especially in calculus and trigonometry, use radians to simplify calculations involving angles and circular functions.
Can I convert degrees to radians without a calculator?
Yes, by using the formula radians = degrees × (π / 180) and knowing the value of π, you can manually convert degrees to radians, though calculators make it easier for precise results.
What is the significance of π in degree-to-radian conversions?
π (pi) is fundamental because it relates the circumference of a circle to its diameter, and using π in conversions aligns angle measurements with the circle’s natural geometry, making calculations consistent and accurate.
