1. What is a UK Percentage Calculator?

Definition: This calculator computes the percentage that a part represents of a whole, following the standard UK mathematical formula.

Purpose: It helps students, professionals, and anyone needing to calculate percentages for various applications including finance, statistics, and everyday calculations.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Part — The portion of the whole you're measuring (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.

A: The calculator will still work, giving you a percentage greater than 100%, which is valid in cases like growth calculations.

Q2: Can I calculate percentage decrease?
A: Yes, use the difference between original and new value as the "part" and original value as the "whole".

Q3: Why does the whole need to be greater than zero?
A: Division by zero is mathematically undefined and would produce an error.

Q4: How precise are the results?
A: Results are shown to 2 decimal places for most practical applications.

Q5: Can I use this for financial calculations?
