Questions fréquentes

Why multiply by π and divide by 180?

Because 180° equals π radians, so the conversion factor is π/180.

Can I convert radians to degrees with this calculator?

No, this calculator only converts degrees to radians. Use the inverse formula (radians × 180/π) for the reverse.

What is the radian value of 360°?

360° equals 2π radians, approximately 6.2832.

Degrees to Radians

radians = degrees × (π / 180)

Multiply the angle in degrees by π divided by 180 to get the angle in radians.

Example:

Input: degrees = 45

Calculation: 45 × (π / 180)

Result: ≈ 0.7854 rad

Cas d'utilisation réels

Où ce calcul apparaît dans la vie quotidienne.

Trigonometry

Convert angles to radians for sine, cosine, and tangent calculations in math and physics.

Example: sin(30°) = sin(π/6)

Programming

Many programming languages use radians for trigonometric functions, so convert degrees to radians.

Example: Math.sin(degrees * Math.PI / 180)

Engineering

Angular measurements in engineering often require radian units for rotational calculations.

Example: Angular velocity in rad/s

Conseils et erreurs courantes

Tips

Remember: 180° = π radians, 90° = π/2, 360° = 2π.
Use the constant π ≈ 3.14159 for manual calculations.
For quick mental conversion, multiply degrees by 0.0174533 (π/180).
Check your result: 1 radian ≈ 57.2958°.

Common Mistakes to Avoid

Forgetting to divide by 180, which gives degrees × π instead of radians.
Using 3.14 instead of π, leading to slight inaccuracies.
Confusing radians with degrees in trigonometric functions.
