How This Tool Works
This ratio calculator helps you solve for a missing value in a ratio (A:B = C:D) and provides a visual representation of the ratio A:B. This is useful for scaling designs, recipes, or any other proportional relationships.
Ratio Calculation
The core formula used is `D = (B * C) / A`. The tool takes the three known values and automatically solves for the fourth, displaying the result in the disabled input field. All calculations are performed instantly in your browser.
Visual Representations
- Pie Chart: The pie chart visually divides a whole into the two parts of the ratio (A and B).
- Parts Bar: This bar shows the proportional relationship between A and B in a linear format.
- Ratio Rectangle: A rectangle is drawn with its width and height proportional to the ratio A:B, helping you visualize aspect ratios.
