Conversion Formula
The formula to change degrees into radians is: radians = degrees * π / 180. This is because 180 degrees equals π radians. By multiplying degrees by π divided by 180, we get the equivalent in radians, which is the standard angular measurement in mathematics and physics.
For example, if you want to convert 195 degrees, you multiply 195 by π and then divide by 180: (195 * π) / 180. This simplifies to approximately 3.4043 radians, showing how the formula works in real calculation.

Conversion Definitions
Degrees
Degrees are a unit of measurement for angles, defining a full circle as 360 equal parts. They are commonly used in navigation, geography, and everyday measurements, providing a familiar way to describe the size of an angle or rotation in two-dimensional space.
Rad
Radians are a mathematical unit for measuring angles, based on the radius of a circle. One radian equals the angle at which the arc length equals the radius, making it useful in calculus and advanced geometry because of its natural relation to circle properties.
Conversion FAQs
How do I convert 195 degrees into radians manually?
Multiply 195 by π and divide by 180, which directly applies the conversion formula. Simplify the expression to get the radian value; in this case, approximately 3.4043 radians, providing an exact measure without electronic tools.
Is there a quick way to estimate radians for degrees close to 180?
Yes, for degrees near 180, you can approximate radians by understanding that 180 degrees equals π radians. So, 185 degrees is about 1/4 of a radian more than π, which helps in quick estimations for similar angles.
Why are radians used instead of degrees in calculus?
Because radians relate directly to the properties of circles and the derivatives of trigonometric functions, calculations become simpler and more natural. Radians simplify formulas involving arc length, angular velocity, and integrals.
