Frequently Asked Questions — Radians to Degrees
Question: How many degrees is 1 radian?
Answer: 1 radian = 57.2957795131 degrees. This comes from the definition: 1 rad = 180°/π, since a full circle is 2π radians = 360°.
Question: How do I convert radians to degrees?
Answer: Multiply the radians by 180/π (≈ 57.2958). For example, 2 rad × 57.2958 ≈ 114.59°.
Question: What is π radians in degrees?
Answer: π radians = 180° exactly. This is a straight angle (a half-turn of a circle).
Question: What is 2π radians in degrees?
Answer: 2π radians = 360° — a full circle. One complete revolution equals 2π ≈ 6.2832 radians.
Question: What is π/2 radians in degrees?
Answer: π/2 radians = 90° — a right angle. Similarly, π/4 rad = 45° and π/3 rad = 60°.
