Mistakes to avoid

Mixing similar-sounding units

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

Forgetting squared and cubed units

Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.

Dropping the units

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

Background

Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.

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.

A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
