1. What is a Ratio to Percentage Calculator?

Definition: This calculator converts a ratio (part to whole) into its equivalent percentage value.

Purpose: It helps in understanding proportions by converting them to the more intuitive percentage format.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Percentage — The resulting percentage value (%)
• Part — The portion of the whole (unitless)
• Whole — The total or reference value (unitless)

Explanation: The part is divided by the whole to get the ratio, then multiplied by 100 to convert to percentage.
