📖 About Unit Conversions
Unit conversion is essential in science, engineering, cooking, travel, and everyday life. The metric system (SI) is used globally, while the imperial system is still common in the US and UK. This converter supports 7 major categories with over 50 individual units.
All conversions are performed using precise mathematical ratios and formulas. Temperature conversions use the standard Celsius-Fahrenheit-Kelvin formulas rather than simple multiplication, ensuring accuracy.

°F = °C × 9/5 + 32. K = °C + 273.15. Temperature is unique because it doesn't use simple multiplication — it requires both multiplication and addition due to different zero points.
GB (gigabyte) uses decimal prefixes: 1 GB = 1,000,000,000 bytes. GiB (gibibyte) uses binary prefixes: 1 GiB = 1,073,741,824 bytes. Operating systems often mix these, which is why a "256 GB" drive shows as ~238 GB in your OS.
