Number Formatter
Format numbers with thousand separators, decimal places, currency symbols or scientific notation. Supports multiple locale formats for global use.
About This Tool
Numbers appear differently across different countries and use cases. In the United States, a million is written 1,000,000 — but in Germany it's 1.000.000, and in France it's 1 000 000. Add currency symbols, decimal precision and scientific notation to the mix, and it's easy to produce incorrectly formatted numbers that confuse readers or break data imports. QuickKit's Number Formatter lets you configure thousand separators, decimal places, currency symbols and scientific notation, then instantly shows the result using the browser's built-in Intl.NumberFormat API.
Features
- ✓Locale-aware Thousand Separators — Choose from comma (US/UK), dot (European), space (French) or no separator — covering the most common international formats.
- ✓Decimal Place Control — Set any number of decimal places from 0 to 20. The number is rounded to fit the specified precision.
- ✓Currency Symbols — Prepend a currency symbol (USD, EUR, GBP, JPY, CNY, TWD) to produce properly formatted currency strings like "$1,234.56".
- ✓Scientific Notation — Enable scientific notation to express very large or very small numbers in exponential form (e.g. 1.23e+6).
FAQ
- Why does the European format use dots for thousands?
- Different regions use different conventions. Germany, France, Italy and many other European countries use a dot (or space) as the thousand separator and a comma as the decimal separator — the opposite of the US convention.
- Can I combine a currency symbol with European formatting?
- Yes — the tool uses the browser's Intl.NumberFormat API, which correctly applies the currency symbol and formatting rules together. However, some currency+locale combinations may produce unexpected placement of the currency symbol.
- What happens if I type a number with existing commas?
- The tool strips existing commas before parsing, so you can paste formatted numbers from spreadsheets or documents without errors.
