1. What is a Percentage Calculator?

Definition: This calculator computes the percentage that one number (the part) is of another number (the whole).

Purpose: It helps users quickly determine percentages for various applications like discounts, statistics, finance, and more.

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)
• Percentage — The result expressed as a percentage (%)

Explanation: The part is divided by the whole to get a decimal value, which is then multiplied by 100 to convert it to a percentage.

3. Importance of Percentage Calculation

Details: Percentage calculations are fundamental in many areas including finance (interest rates), statistics (data analysis), shopping (discounts), and academic grading.

4. Using the Calculator

Tips: Enter the part and whole values (both must be positive numbers, and whole cannot be zero). The calculator will automatically compute the percentage.

5. Frequently Asked Questions (FAQ)

Q1: What if my part is larger than the whole?
A: The calculator will still work, giving you a percentage greater than 100%, which is valid in cases like growth rates or performance exceeding targets.

Q2: Why can't the whole be zero?
A: Division by zero is mathematically undefined. You cannot calculate what percentage something is of nothing.

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 (increase/decrease), you would need a different calculator that compares old and new values.

Q5: Is this calculator specific to the UK?
A: While branded as "UK", percentage calculations work the same worldwide. The name reflects the style of Google's UK calculator.
