About this tool
Length, weight, speed, data, and area conversions use fixed, standard multipliers (for example, exactly 25.4 millimeters per inch); temperature uses the correct Celsius/Fahrenheit/Kelvin formulas rather than a simple ratio, since those scales don't share a zero point. The "Data" category here uses decimal multiples (1 KB = 1,000 bytes) — for the binary (1 KiB = 1,024 bytes) distinction that matters for file sizes and storage, see the dedicated File Size Converter.
