Mistakes to avoid

Dropping the units

A bare number without a unit is easy to misread later. Always write the unit with the result.

Rounding the factor too early

Using 3 instead of 3.28 for feet per metre introduces an error of almost 9% before you have started.

Mixing similar-sounding units

US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.

Background

Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.

For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.

Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
