Unlike other unit conversions that use simple multiplication, temperature conversion uses formulas. Celsius to Fahrenheit: F = C × 9/5 + 32. Celsius to Kelvin: K = C + 273.15. These formulas are built into the converter, so you just need to enter your value.
Computer systems use binary (base-2), where 2^10 = 1024 is a convenient boundary. 1 KB = 1024 bytes, 1 MB = 1024 KB, etc. The decimal-based units (using 1000) are called kibibyte (KiB), mebibyte (MiB), etc., but the binary definitions are still common in operating systems and storage devices.
All conversions use precise conversion factors and JavaScript's 64-bit floating point numbers. Results are displayed to 6 significant figures. For most practical applications, this level of precision exceeds what you'll need. Very large or small numbers automatically use scientific notation.
Yes, this tool supports both metric (meters, kilograms, liters) and imperial/US customary units (feet, pounds, gallons). Simply select your source unit, enter the value, and choose your target unit. Common conversions like miles to kilometers, pounds to kilograms, and gallons to liters are all available.
