Purpose: It helps compare the relative size of two values by expressing one as a percentage of the other.
The calculator uses the formula:
Where:
Explanation: The smaller number is divided by the larger number, then multiplied by 100 to convert to a percentage.
Details: Percentage calculations are fundamental in statistics, finance, science, and everyday comparisons to understand relative proportions.
Tips: Enter both numbers (smaller first, then larger). Both values must be positive numbers, and the larger number should be greater than or equal to the smaller number.
Q1: What if my numbers are negative?
A: This calculator only works with positive numbers. For negative values, consider using absolute values.
Q2: What if the "smaller" number is actually larger?
A: The calculator will still work, but the result will be greater than 100%, indicating the first number is larger than the reference number.
Q3: How precise are the results?
A: Results are shown with 2 decimal places for most percentages, providing sufficient precision for most applications.
Q4: Can I calculate percentage decrease?
A: Yes, this calculator can be used for percentage decrease by putting the decreased value as the smaller number and original value as the larger number.
Q5: What's the difference between this and percentage change?
A: This shows what percent one number is of another, while percentage change shows the difference between two numbers as a percentage of the original value.
