Free / no pricing configured

What it does

Converts a value from a source unit to a target unit and returns the result, the physical dimension, and a formatted string. Conversions are exact and dimension-checked: converting between incompatible dimensions (e.g. mass to length) is rejected rather than guessed.

Primary use cases

Length, mass, temperature, area, volume, speed, data-size, energy, pressure, power, and angle conversions.
Normalizing measurements between metric and imperial.
Any "X in unit A is how many of unit B" question.

Good to know

Units are written by name (e.g. mile, kilogram, degree_Celsius, kilometer/hour). Compound and SI-prefixed units are supported (e.g. meter**2, MB). Use list_units to discover valid names. Distinct from currency, which handles money. Computed locally.
