How It Works

  1. Write down the decimal number (e.g., 0.457).
  2. Move the decimal point **two places to the right** (e.g., 45.7).
  3. Add the "%" symbol at the end (45.7%).
  4. If there are empty spaces, fill them with zeros (e.g., 0.5 → 0.50 → 50%).

Formula:

Decimal × 100 = Percentage

Conversion Formula

The formula to convert a decimal to a percentage is simple: **Percentage = Decimal × 100** Values less than 1 (0.5, 0.2) become percentages less than 100%. Values greater than 1 (1.5, 2.0) become percentages greater than 100%.

Why Convert?

Decimals are often used in math equations (like 0.05 for tax), but percentages are easier for people to understand in conversation ("5% tax"). This calculator bridges that gap.

Examples

Example A: Standard

Result: 0.85 × 100 = 85%

Example B: Small Decimal
