Formula
Percentage = Decimal × 100. The calculator takes the input value and shows both the decimal form and the percentage form side by side.
Worked example
0.25 = 25%. 1.5 = 150%. 0.005 = 0.5%. Enter any decimal to see its percentage equivalent.
Practical guidance
When to use each form
Use percentage for communication and display (25%, not 0.25). Use decimal for calculations and spreadsheet formulas. Many formulas expect decimal form (e.g., 0.08 for 8% interest rate). Convert before plugging into equations.
Percentages above 100%
Values above 1.0 produce percentages above 100%, which is perfectly valid. A 150% increase means the value is 2.5× the original. The calculator handles all decimal inputs, including values above 1 and negative values.
