1. What is a Percentage Calculator?

Definition: This calculator computes what percentage one number is 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 of the whole you're measuring
• Whole — The total or reference amount

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

3. Importance of Percentage Calculation

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

4. Using the Calculator

Tips: Enter the part and whole values. The whole must be greater than zero. The result shows what percentage the part is of the whole.

5. Frequently Asked Questions (FAQ)

Q1: What if my whole is zero?
A: Division by zero is undefined. The whole must be greater than zero for a valid calculation.

Q2: Can percentages be over 100%?
A: Yes, if the part is larger than the whole, the percentage will exceed 100%.

Q3: How precise are the results?
A: Results are shown to two decimal places for most practical applications.

Q4: Can I calculate percentage change with this?
A: For percentage change between two values, you would need a different calculator that uses the change formula.

Q5: What's the difference between percentage and percentile?
A: Percentage is a proportion out of 100, while percentile indicates a value below which a given percentage falls in a distribution.
