Free Unit and Currency Converters — Metric, Imperial and More

Unit conversion is a daily need for professionals, students, travellers, and home cooks working across different measurement systems. The metric system used by most of the world and the imperial system primary in the United States are incompatible in ways that cannot be solved by simple multiplication alone — temperature conversion between Celsius and Fahrenheit requires both multiplication and addition, making mental arithmetic unreliable.

The colour converter handles the three major colour formats used in web design and digital art: HEX codes used in HTML and CSS, RGB values used in image editing software, and HSL used by modern CSS frameworks. Converting accurately between these formats is essential for maintaining consistent brand colours across different tools and platforms.

The currency converter covers 20 major world currencies and shows all conversions simultaneously when you enter an amount — useful for travellers comparing costs in multiple currencies, or businesses invoicing international clients. All conversions update instantly without page reloads.
