Converters

Unit and currency converters

Length, weight, area, volume, speed, pressure, energy, power, angles, fuel consumption, temperature, digital storage and currency. Every conversion checks the dimension: mixing incompatible units is refused, not answered with a meaningless number. Currency conversion uses the rate you provide.

Function guide

What it does: Converts length (millimetre to mile) and mass (milligram to tonne) within the units of the list.
What it is for: For recipes, shipping, part measurements, travel distance and any number that arrives in a unit other than yours.
When to use it: Use it when origin and target belong to the same dimension. Length and mass are different dimensions: converting kilos into metres is refused.
What to fill in: Value, source unit and target unit, chosen among the length and mass options.
Formula: Each unit has a fixed factor to the base unit of its dimension (metre and kilogram). The conversion is value × source factor ÷ target factor.
What each result means: The value in the target unit. When the dimensions do not match, an incompatible-unit error appears instead of a meaningless number.
Worked example: 1 mile gives 1.609344 km; 70 kg give 154.32 lb.

Each calculation's assumptions are in the function guide — no constant stays hidden.
