convert_units

Convert a value from one unit to another.

Supports 10 categories: length, mass, volume, area, speed, time,
temperature, digital storage, energy, and pressure.
Units must be in the same category (e.g. both length units).

Examples: kilometer→mile, pound→kilogram, fahrenheit→celsius,
gigabyte→mebibyte, kilowatt_hour→btu, psi→bar.

Parameter	Type	Required	Description
`value`	`number`	required	The numeric value to convert.
`from_unit`	`string`	required	Source unit (e.g. 'kilometer', 'pound', 'fahrenheit').
`to_unit`	`string`	required	Target unit (e.g. 'mile', 'kilogram', 'celsius').
