Details & limits

A fixed catalog of six dimensions. No currency or live data. Temperature cannot fall below absolute zero.

Which definitions are used?

Conversions use SI relationships, international inches and feet, avoirdupois pounds and US liquid gallons. Units from different dimensions cannot be mixed. Floating-point results are rounded for display; currency conversion is not included.

Use units from the same measurement category

The catalog includes metric and selected imperial units, such as centimetres and inches or kilograms and pounds. Fluid ounces and mass ounces are distinct; the volume options use US fluid ounces and US liquid gallons. Temperature conversion accounts for offsets and rejects values below absolute zero. Currency conversion and live exchange rates are outside this tool's scope.
