Convert the quantity without changing its meaning
Unit converters express one physical or digital quantity on another compatible scale. This directory includes familiar dimensions such as length, area, volume, mass, speed, temperature, pressure, energy, storage, and transfer rate.
A factor conversion is valid only when both units describe the same dimension and reference basis. Temperature offsets, gauge versus absolute pressure, binary data units, and density-dependent conversions require special handling rather than simple multiplication.
