How do different countries format numbers?

US/UK: 1,234,567.89. Germany/France: 1.234.567,89. India: 12,34,567.89. Switzerland: 1'234'567.89. The tool supports all major regional conventions.

Can I format as currency?

Yes. Select any currency (USD, EUR, GBP, JPY, etc.) and choose the locale — the tool applies the correct currency symbol placement, spacing, and decimal format for that currency's convention.

What is compact notation?

Compact notation abbreviates large numbers: 1,200,000 becomes 1.2M, 45,000 becomes 45K. Useful for dashboards, chart axis labels, and displays where space is limited.

What is engineering notation?

Engineering notation is like scientific notation but restricts the exponent to multiples of 3 (kilo, mega, giga, etc.), aligning with SI prefixes: 45,000 = 45 × 10³ instead of 4.5 × 10⁴.
