Pie Chart Angle Calculator
Enter category labels and values (one per line) to compute the angle and percentage of each slice in a pie chart.
Example: Marketing 30
| Label | Value | Percentage | Angle (degrees) |
|---|---|---|---|
| Marketing | 30 | 30.00% | 108.00° |
| Sales | 45 | 45.00% | 162.00° |
| Support | 25 | 25.00% | 90.00° |
Total value: 100
How to Use This Calculator
- Enter each pie slice on a new line with label and value.
- Ensure values are non-negative numbers.
- Review calculated percentages and angles for constructing the pie chart.
- Use the output to draw pie charts accurately or feed into visualization tools.
Formula
Percentage = (slice value / total) × 100%
Angle = (slice value / total) × 360°
Total = Σ slice values
Full Description
Pie charts visualize parts of a whole. Each slice’s angle is proportional to its share of the total. This calculator converts raw values into degrees and percentages, enabling precise chart construction without manual calculations.
Frequently Asked Questions
Can values be zero?
Yes, but zero-valued slices contribute 0° and 0%.
Does order matter?
No. Order affects the table display only. You can rearrange slices when drawing the chart.
What if total is zero?
Angles cannot be computed when the total is zero. Ensure at least one positive value.
Are percentages guaranteed to sum to 100%?
Yes, aside from minor rounding differences shown in the table.
