1. What is a Percentage Calculator?

Definition: This calculator computes the percentage that one number represents of another number.

Purpose: It helps in various mathematical, financial, and statistical calculations where relative proportions need to be determined.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Part — The portion you want to find the percentage of (unitless)
• Whole — The total or reference amount (unitless)

Explanation: The formula divides the part by the whole to get a decimal value, then multiplies by 100 to convert it to a percentage.

3. Importance of Percentage Calculation

Details: Percentage calculations are fundamental in statistics, finance, science, and everyday life for comparing proportions and analyzing data.

4. Using the Calculator

Tips: Enter the part and whole values (both must be positive numbers). The whole value cannot be zero.

5. Frequently Asked Questions (FAQ)

Q1: What if my whole value is zero?
A: Division by zero is undefined. The whole value must be greater than zero.

Q2: Can I use decimal numbers?
A: Yes, the calculator accepts decimal values for both part and whole.

Q3: What's the maximum percentage possible?
A: There's no theoretical maximum, but percentages over 100% indicate the part is larger than the whole.

Q4: How precise are the results?
A: Results are displayed with 2 decimal places for precision.

Q5: Can I calculate percentage change with this?
A: For percentage change, you would need a different formula: ((New - Old)/Old) × 100.
