About this collection

Practical unit conversion tools, without the clutter.

Unit mistakes are easy to make because familiar labels can hide different standards. A gallon is not always the same gallon, storage units may use decimal or binary scales, and a rounded value can drift across repeated calculations.

These converters put the source unit and destination unit side by side. Enter the value once, choose both units deliberately, and keep enough precision for the job you are doing.

Worth checking: For engineering, laboratory or regulated work, confirm the required standard and rounding rules before relying on a converted value.
