Radians to Degrees Calculator

Published on: January 26, 2025

This Radians to Degrees Calculator helps you convert an angle from radians to degrees. It uses the formula degrees = radians × 180 / π, which changes the angle into degree form used in many geometry and trigonometry problems. Multiply the radian value by 180, then divide by π to get the answer in degrees. It is a simple way to check answers, understand angle conversion, and practise basic trigonometry step by step.

Step-by-step method

  1. Identify what is given.
  2. Write the conversion formula.
  3. Substitute the value and calculate.

Formula

Example 1: θ = π/2

Step 1 - Identify what is given.

In this problem: The given angle is θ = π/2 radians.

θ=π/2

Step 2 - Write the conversion formula.

In this problem: Use the conversion formula: degrees = radians × 180 / π.

degrees=radians×

=90°

Final answer: 90°

Example 2: θ = 3π/4

Step 1 - Identify what is given.

In this problem: The given angle is θ = 3π/4 radians.

θ=3π/4

Step 2 - Write the conversion formula.

In this problem: Use the conversion formula: degrees = radians × 180 / π.

degrees=radians×
