Mistakes to avoid

Multiplying when you should divide

Converting to a smaller unit gives a bigger number, and converting to a larger unit gives a smaller one. If your answer moves the wrong way, you have inverted the factor.

Mixing similar-sounding units

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

Dropping the units

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

Background

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.

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.

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