Como usar
Percent literally means 'per hundred'. To go from a percentage to a decimal, divide by 100 (move the point two places left): 25% → 0.25. To go back, multiply by 100: 0.25 → 25%.
Fractions are always reduced to lowest terms, so 25% comes back as 1/4 rather than 25/100, and 12.5% as 1/8.
Results are rounded to remove binary floating-point noise, so 10% converts to exactly 0.1. Fractions honour up to 6 decimal places of the percentage; repeating values such as 33.333…% are marked as approximate.

Frequently Asked Questions
- How do I convert a percentage to a decimal?
- Divide the percentage by 100. For example, 25% becomes 0.25. The calculator does this instantly and exactly.
- What does '1-in-N' probability mean?
- It expresses a probability as a ratio of 1 success in N trials. For instance, 25% probability is equivalent to 1 in 4. The calculator converts your percentage to this format.
- Can I convert a decimal back to a percentage?
- Yes, the calculator also supports converting decimals to percentages. Simply enter a decimal like 0.75, and it will show 75%.
Tips & Common Mistakes
Tips
- Use the calculator to verify your manual conversions, especially when dealing with repeating decimals like 33.33%.
- When converting to odds, remember that odds represent the ratio of success to failure, not the probability itself.
- For exact fraction results, the calculator reduces fractions to their simplest form automatically.
- Double-check your input format: percentages should be entered as numbers without the '%' symbol unless specified.
Common Mistakes to Avoid
- Forgetting to divide by 100 when converting a percentage to a decimal manually.
- Assuming that 1-in-N odds are the same as the probability percentage; they are different representations.
- Entering a percentage as a decimal (e.g., 0.25 instead of 25) without adjusting the conversion.
