How do I convert category values into pie chart angles?

To convert category values into angles for a pie chart, follow these steps:

• Find the Total of All Values
  Add up all the category values to get the total.
  Example: If you have 3 categories with values 20, 30, and 50 →
  Total = 20 + 30 + 50 = 100
• Find the Fraction of Each Category
  Divide each category value by the total.
  Example: For the first category → 20 ÷ 100 = 0.2
• Convert the Fraction into an Angle
  Multiply the fraction by 360° (because a circle has 360°).
  Example: 0.2 × 360° = 72°
• Repeat for All Categories
  Do this for each category to find its corresponding angle.

Example

When you draw the pie chart, make sure all angles add up to 360°.
